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....

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.

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

David loves to cook! He knew 21 recipes before starting cooking school and he learns 2 recipes
every 1 one week. An equation to represent that is y = 21 + 2x where x represents number of
weeks and y represents number of recipes.
His friend Sarah believes that if he attends school for 10 weeks that means he knows 42 recipes.
Explain if she is correct.
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.
Answer:
Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.
Step-by-step explanation:
To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:
y = 2x + 21
42 = 2(10) + 21
42 = 20 + 21
42 [tex]\neq[/tex] 41
Sarah is wrong.

Step-by-step explanation:
AB is the shortest segment in ABC
AC = 2AB
Find the unknown angle measured
Answer:
b=121, a and c=59
Step-by-step explanation:
b and 121 are congruent angles, so they are equal to each other.
each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.
a and c are congruent angles so they are also equal to each other

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.

Step-by-step explanation:
The points are:
[tex]A(-2, 5)[/tex]
[tex]B(-2, -7)[/tex]
[tex]C(-6, -4)[/tex]
Considering the sides as vectors, we have:
[tex]\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}[/tex]
Once
[tex]\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)[/tex]
[tex]\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)[/tex]
[tex]\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)[/tex]
[tex]\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}[/tex]
[tex]\Vert \overrightarrow{AB} \Vert = \sqrt{x^2 + y^2} = \sqrt{0^2+(-12)^2} = \sqrt{144}= 12[/tex]
[tex]\Vert \overrightarrow{CB} \Vert = \sqrt{x^2 + y^2} = \sqrt{4^2+(-3)^2} = \sqrt{16+9}= 5[/tex]

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
