Answer:
25
Step-by-step explanation:
25 should be chosen as the common denominator. 5 is a possible common denominator because the other fraction has a denominator of 5 and 25 is divisible by 5, however, the numerator cannot be evenly divided by 5. Attempting to do so would cause a much more difficult equation. On the other hand, the denominator 5 can be changed to 25 by multiplying by 5, and 4 can also be changed by multiplying by 5.
4/5 x 5 = 20/25
6/25 - 20/25 = -14/20 = -7/10

work:
3/2 + 2m = 7/2
3/2 (-3/2) + 2m = 7/2 (-3/2) subtract 3/2 from both sides
2m = 2
2m/2 = 2/2 divide 2 on both sides

Translate One-third of a number is 14 into an equation
Answer:
1/3x=14
answer for x is 42
Step-by-step explanation:
x represents the original number and 1/3 of the number equals 14. So 1/3x=14
So therefore 1/3x=14 which x = 42 in case if you were wondering.
Find the length of YZ
Answer:
[tex]YZ = 19cm[/tex]
Step-by-step explanation:
To figure out what line YZ equals, we must first find x. And to do this, let's set up an equation.
Firstly, we know that XY is 8cm, and XZ is 4x+3. So, we know that XY + YZ will equal XZ. Let's set that up:
[tex]8 + 2x+7=4x+3[/tex]
Combine like terms.
[tex]2x+15=4x+3[/tex]
Subtract 2x from both sides.
[tex]15=2x+3[/tex]
Subtract 3 from both sides.
[tex]12=2x[/tex]
Divide both sides by 2.
[tex]6=x[/tex]
Now, we just need to plug 6 into the equation of YZ.
[tex]2(6)+7[/tex]
[tex]12+7[/tex]
[tex]YZ = 19[/tex]

Sean spent $41.20 ordering books from an online
store. The shipping and handling charge was 5%
of the total order. How much did Sean spend on
shipping and handling?
A. $0.42
B.
$0.85
C. $2.06
D. $8.24
Answer:
the awnser is c
Step-by-step explanation:
first you take 41.20$ and you subtract you're 5%
therefore that gives you 39.14$
subtract 39.14$ from 41.20
and you get a left over of 2.06$
therefore c is you're awnser
A percentage is a number or ratio expressed as a fraction of 100.
The amount spent on shipping and handling charges is $2.06.
What is a percentage?A percentage is a number or ratio expressed as a fraction of 100.
Example:
50% = 50 / 100 = 1/2
20% = 20 / 100 = 1/5
25% = 25 / 100 = 1 / 4
10% = 10 / 100 = 1 / 10
We have,
Total spending on books = $41.20
Shipping and handling charges = 5% of $41.20
The amount spent on shipping and handling charges:
= 5% of $41.20
= 5/100 x 41.20
= 5/100 x 4120/100
= 5 x 4120 / 10000
= 20600 / 10000
= $2.06
Thus the amount spent on shipping and handling charge is $2.06.

Find the value of this triangle!
Answer:
x=35
y=145
z=25
Step-by-step explanation:
(do first)x:
55 + 90 = 145
180-145=35
(do last)y:
25+10=35
180-35=145
(do second)z:
65+90=155
180-155=25
Answer:
x = 35, y = 145, z = 25
Step-by-step explanation:
All triangles' angles have a sum of 180°. Because we know this, we can solve the first triangle easily.
180 = x + 90 + 55
180 = x + 145
35 = x
Angles x and y are what we call suplementary angles. This means they have a sum of 180°.
180 = 35 + y
145 = y
Once again, we know that triangles have a sum of 180°. So the next triangle should now be easy to solve.
180 = 10 + 145 + z
180 = 155 + z
25 = z

Step-by-step explanation:
This might look strange, but I would begin by adding 4y to both sides.
12x = 20 + 4y Subtract 20
12x - 20 = 4y Divide both sides by 4
12x/4 - 20/4 = 4y/4 Combine

Part A
We have 20 cards, 4 of which are kings (one of each suit). The probability of getting a king on the first draw is 4/20 = 1/5.
Answer: 1/5===========================================================
Part B
We have 20-4 = 16 cards that aren't a king out of 20 total.
The probability of getting a non-king card is 16/20 = 4/5
After selecting the first card and not putting it back, we have 20-1 = 19 cards left. Four of which are a king, so 4/19 represents the probability of getting a king on this draw.
So (4/5)*(4/19) = 16/95 is the probability of getting a king on the second draw where the first draw is not a king.
Answer: 16/95===========================================================
Part C
16/20 is the probability of getting no kings on the first draw
15/19 is the probability of getting no kings on the second draw (notice I stepped the values down by 1)
14/18 is the probability of getting no kings on the third draw
Multiplying out the fractions gives
(16/20)*(15/19)*(14/18) = 28/57
I skipped a few steps when multiplying the fractions but you get the idea.
The probability of drawing 3 cards, none of which are a king, is 28/57
Subtract this from 1 to get the complementary probability
1-(28/57) = 57/57 - 28/57 = (57-28)/57 = 29/57
This works because we have two choices: either we get no kings, or we get at least one king. So that's why the two events are complementary and their probabilities add to 1.

a) Find f(1) =
(1) b) Find f(5) =
(1)
Answer:
f(1) = - 5, f(5) = 6
Step-by-step explanation:
(a)
f(1) with x = 1 is in the interval x ≤ 1 , thus
f(1) = - 5
(b)
f(5) with x = 5 is in the interval x > 1 , thus f(x) = 2x - 4 , so
f(5) = 2(5) - 4 = 10 - 4 = 6

The ratios 5:3 and 10:6 are equivalent ratio
Is the ratio 15:12 equivalent to these?? Explain your reasoning
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3
Given,
5:3 and 10:6 are equivalent ratios.
We need to see whether these ratios are equivalent to 15:12.
What are proportional ratios?The ratios which are equal are called proportional ratios.
Example:
1:2 = 5:10 = 6:12 = 7:14
5/10 = 1/2
6/12 = 1/2
7/14 = 1/2
We have,
5:3 and 10:6
- 5/3
- 10/6 = 5/3
We have,
15:12
= 15/12
= 3x5/3x4
= 5/4
We see that 5:3 and 10:6 are not equivalent to 15:!2.
Thus,
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3
