8 0

The answer is 2

Step-by-step explanation: 100% is the highest score you can have  . then you have to divide 25 by 100 because 25 is the total amount of questions ,you should get 4,wich means each question is worth 4 points.

18 correct is a score of 72

20 correct is a score of 80

4x2=8 wich you need 8 more to get to 80 from 72

feel free to ask for more help :)

2/3A=-24 <br><br> this the last one that I need help on.

You can answer this question in numerous ways but one simple way is by multiplying fractions. 

<span>2/3 of 24 is also 2/3 of 24/1 </span>
<span>To get the answer, you must multiply 2/3 by 24/1 </span>

<span>To do this, you multiply the numerator (the top number) by the other numerator. That is, 2 x 24 . The answer is 48. </span>

<span>Then, multiply the denominators (the bottom numbers) by each other. That is, 3 x 1. The answer is 3. </span>

<span>The answer is 48/3. But you must continue simplifying. </span>

<span>What is 48 divided by 3? 16. </span>

<span>If you do not understand it that way, think of it in a simpler way. </span>

<span>Say there are 24 slices of pieces. </span>

<span>What is one third of those 24 slices? </span>

<span>24 divided by 3 = 8. </span>

<span>Now you want TWO thirds. So all you do is multiply 8 by 2. </span>

<span>That gives you 16.

A clothing store sells a customer 3 T-shirts and 4 pairs of shorts for $83.
ss7ja [257]
3t + 4s = $83
4t + 1s = $50 (x 4)

16t + 4s = $200
3t + 4s = $83 (minus them£

13t = $117 (divide by 13)

t = $9

sub t into first equation.

3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14

t = $9
s = $14
