Answer:
She will take 10 weeks to save the money for the DVD player
Step-by-step explanation:
Let w = Lianne's weekly allowance.
The DVD player costs 2 1/2 times her weekly allowance, thus
DVD cost = 5/2w
She gets w every week but spends 3/4w on other things, thus the remaining money is
Weekly savings =w - 3/4w = 1/4w
To know the number of weeks needed, we divide the DVD cost by the weekly savings:
[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]
Operating:
[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]
N = 10
She will take 10 weeks to save the money for the DVD player
Dr. Betz, a vet, is running a free rabies clinic. He estimates that it will take him 12 minutes for each animal he treats. Dr. Betz has already seen 20 animals, the last of which was a shaggy dog. Write an equation for how many minutes Dr. Betz worked. How long did Dr. Betz work at the rabies clinic if he saw 20 more animals after the shaggy dog?
Answer:
equation: y = 12x
Dr. Betz worked for 8 hours.
Step-by-step explanation:
To write the equation we'll use the form y = mx, where y represents the amount of time the Doctor worked, m is the amount of minutes it takes to treat each animal, and x is how many animals have been treated. We know the value of m is 12, so let's put that into the equation:
y = 12x
Now we have our equation. We can use it to see how long Dr. Betz worked. He treated a total of 40 animals - 20 including the shaggy dog, and 20 after the shaggy dog. let's replace x with 40:
y = 12(40)
Now solve:
y = 480
Dr. Betz worked for 480 minutes. There are 60 minutes in an hour. Divide 480 by 60 to find out how many hours Dr. Betz worked for:
480/60 = 8
Dr. Betz worked for 8 hours.
Renaldo will write StartFraction 3 over 20 EndFraction as a decimal. Which of the following methods should he use?
A:Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
B:Multiply the fraction by One-fifth to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
C:Multiply the fraction by StartFraction 33.3 over 33.3 EndFraction to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
D:Multiply the fraction by 33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
Answer:
Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Option A is correct.
Step-by-step explanation:
Renaldo will write [tex]\frac{3}{20}[/tex] as a decimal.
We need to choose methods he should use.
To convert fraction into decimal we need to make denominator the multiple of 10
If we multiply 20 by 5 we get 100, so multiplying the given fraction [tex]\frac{3}{20}[/tex] by [tex]\frac{5}{5}[/tex] because we need to multiply both by numerator and denominator
So, [tex]\frac{3}{20}\\=\frac{3}{20}\times \frac{5}{5}\\=\frac{15}{100}\\=0.15[/tex]
So, Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Option A is correct.
Answer:
it A. Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

13. Find the value of x.
(5x + 2) (11x - 30)
I need help
Answer:
x=13
Step-by-step explanation:
5x+2+11x-30=180 (co-interior angles add to 180)
16x-28=180
16x=208 (divide both sides by 16)
x=13
The measure for x is 13.
What are Co- interior Angles?Co-interior angles are located on the same side of a transversal and between two lines. The two marked angles in each diagram are referred to as co-interior angles. Co-interior angles are supplementary if the two lines are parallel since they add to 180 degrees.
Given:
Angles are (5x+2) and (11x- 30).
So, 5x+2+11x-30=180 (co-interior angles add to 180)
16x-28=180
16x=208
x=13
Hence, the measure for x is 13.

Use the following word problem for questions 7 and 8 below. A total of 564 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
7) Which equation below could be used to find the number of adult tickets that were sold. *
7 + 8x = 564
7x + 8x = 564
A + 3A = 564
A + 3 = 564
3A = 564
Answer:
A+3A=564
Step-by-step explanation:
As A is the no. of Adult tickets solds are denoted as 'A' and since the no. of Student tickets sold are 3 times of the adult tickets sold meaning 3 times A, denoted as 3A, when we sum them up, it equates to the total no. of tickets sold....

solve |x - 6| + 8 = 17
Answer:
x=15
Step-by-step explanation:
(x-6)+8=17 then remove unnecessary parentheses x-6+8=17 then calculate the sum x + 2 = 17 the move constant to the right hand side and change its sign x = 17 - 2 then subtract the numbers x=15 btw you should use photo math that's what I used
|x - 6| + 8 = 17
Subtract 8 from both sides.
|x - 6| + 8 - 8 = 17 - 8
|x - 6| = 9
Set x - 6 to 9 and -9, which leads to two cases.
x - 6 = 9
x = 9 + 6
x = 15
x - 6 = -9
x = -9 + 3
x = -6
Which is the answer?
Plug both values into the original absolute value equation to see which yields a true statement.
Let x = 15
|15 - 6| + 8 = 17
|9| + 8 = 17
9 + 8 = 17
17 = 17
Let x = -6
|-6 - 6| + 8 = 17
|-12| + 8 = 17
12 + 8 = 17
20 DOES NOT EQUAL 17.

Answer:
Angle LMO = 50°
Step-by-step explanation:
1) We need to solve for x.
We know angle LMN = 90°, and that angles LMO and NMO add up to angle LMN. That gives us this equation:
3x + 38 + 10x = 90
Now, we solve for x!
Combine like terms
13x + 38 = 90
Subtract 38 from both sides
13x = 52
Divide both sides by 13
x = 4
Now we know what x is.
2) Plug in x to angle LMO's given value (3x + 38)
3(4) + 38 = angle LMO
12 + 38 = angle LMO
50° = angle LMO
james is following this recipe to make flapjacks.
James uses 375 g of margarine.
How many flapjacks is James making?
Recipe: Makes 8 flapjacks
75 g sugar
125 ml syrup
125 g oats
125 g margarine
30 g sultanas
Answer:
24
Step-by-step explanation:
Take the total amount of margarine used and divide it by the used per batch. 375/125 equals 3. This means James made 3 batches so we multiple the ammount of flapjacks per batch by the number of batches. 3*8 equals 24.
Answer:
24 flapjacks
Step-by-step explanation:
One recipe of flapjacks takes 125g of margarine and James is using 375. To find out how many recipes James is making divide the amount of margarine he is using (375g) by the amount of margarine needed in 1 recipe (125g).
375÷125=3
One recipe makes 8 flapjacks and since James is making 3 recipes you multiply 3 by 8 to get the number of flapjacks that James is making.
8*3=24

A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the length of the third side if the second side is length s?
s - 10
s + 10
2s - 10
2s + 10
Answer:
Step-by-step explanation:
Perimeter 165 cm
1st. 65 cm < 2s
3rd. 10 cm < s
The 2nd side is twice than the first side but 10cm longer than the
3rd side, so it'll be
2nd. 2s + 10
a triangle has a perimeter of 165 cm. the first side is 65cm less than twice the second side. the third side is 10cm less than the second side. write and solve an equation to find the length of each side of the triangle
FIRST, we need variables. Once we define variables, it's much easier to turn this word problem into a math problem.
Let a = first side
Let b = second side
Let c = third side
NOW, we can turn the words into equations:
"a triangle has a perimeter of 165 cm."
a + b + c = 165
"the first side is 65cm less than twice the second side."
a = 2b - 65
"the third side is 10cm less than the second side."
c = b - 10
Before we finish, I have to ask: Who writes problems like this??? Pointless problems like these are why kids don't like math! Ugh. Drives me crazy. It's a shame, because solving math problems really does have a certain satisfaction, once you learn how. [Okay. I'm done. Back to the problem.]
If we could get this to have only one variable, we could solve it. Substitution to the rescue!
a + b + c = 165 (rewrote equation from above)
(2b - 65) + b + (b - 10) = 165 (substituted "a" and "c" from equations above)
See how that works? Let's solve it.
2b - 65 + b + b - 10 = 165 (dropped the parentheses, because there was nothing to distribute, not even a minus sign)
4b - 75 = 165 (combined like terms)
4b = 240 (added 75 to both sides)
b = 60 (divided both sides by 4)
We found the second side! We can find the first and third sides using those equations from above:
a = 2b - 65
a = 2*60 - 65
a = 120 - 65
a = 55
c = b - 10
c = 60 - 10
c = 50
All done.
The lowest and leftmost note on a piano keyboard is an A. The next lowest A is seven white keys to the right. This pattern continues. Write an explicit formula for an arithmetic sequence to represent the position of each A key on the piano, counting from the left. If a piano has 52 white keys, in what position is the key that plays the highest A?
Answer: Not sure but this may help!
Step-by-step explanation:
A = 7 —>
52 keys which means A is 7 keys to the right and there is about 7 A keys. 52 divided by 7 = around 7. I don’t know the question but I need points!

Joe pushes a box with a force of 16 N to the left. Ann pushes the same box from the opposite side with a force of 10 N to the right. What will be the result?
Answer:
the box will move to the left with a force of 6 N
Step-by-step explanation:
Given that:
Force exerted on the box to the left (F1) = 16N
Force exerted on box towards the right (F2) = 10N
Since the forces are a ting in opposite Direction :
Net force :
F1 - F2
16N - 10N = 6N
The net force will be the direction of the greater applied force :
Hence, the box will move to the left with a force of 6 N
