15 = 3*5
64= 2*2*2*2*2*2
There are no common factors so the GCF is 1
$55 this is shown by doing 80/100=0.80. and 0.80*55=this is the answer
<span>The correct answer for this question is that Alice Correa will have spent $6.07 on the cloth overall. This can be worked out through first considering what 5% of the original price will be, so $5.79 / 100 = 0.0579 x 5 = $0.28, so $5.79 + $0.28 = $6.07</span>
The answer would be, it was reduced by 35%
Because you can't solve for two variables at once, you can guess and trial/error.
You can also give x or y any value, and then solve for the opposite variable.
x = 0
y = -36
for example. There are more solutions.
y + 8 = -4(x+7)
-36 + 8 = -4(0+7)
-28 = 0 - 28
-28 = -28
