Answer:

<span>y=−24</span>

Explanation:

<span><span>18</span><span>(5y+64)</span>=<span>14</span><span>(2y+20)</span></span>

multiply both sides by 8:

<span>5y+64=2<span>(2y+20)</span></span>

multiply out brackets:

<span>5y+64=4y+40</span>

subtract 4y from both sides:

<span>y+64=40</span>

subtract 64:

<span>y=40−64=−24</span>

<span>y=−<span>24
</span></span>

Jake ate 55% of a cake. What fraction of the cake did he eat?
7nadin3 [17]

Answer:

11/20

Step-by-step explanation:

To be able to find the fraction of the cake that Jake ate if you know that he ate 55% of it, you have to turn the 55% into a fraction. To do this, first you have to divide the percent by 100:

55/100

Then, you have to simplify the fraction. In this case, you can do it by dividing by 5:

11/20

According to this, the fraction of the cake that Jake ate is 11/20.
