Answer:13.5
Step-by-step explanation:
the answer is 13.5
Since 7y and 5y has the same variable, add them together.
7y + 5y = 12y
We get 12y, so y has to multiply 12 to get 16. I divided 16 by 12, which got me 1.3333333.
16 divide by 12 = 1.33333333
y = 1.33333333 ( 3 keeps going on )
<span> divide 24 by 25 and you keep the whole number the same so the answer would be 87.96</span>
