35
Step-by-step explanation:
19+19.50=38.5
38.5×7=269.5
269.5÷7.70=35
Rearrange the equation for like terms:
7b - 4b <span>- 3b </span>+ 3 + 5 + 2
= 10
I think it is:
A = 9y = 3yx
A = 9y = 3y (3)
A = 9y = 9y
A = 9y
A/9 = y?
The perimeter is twice the sum of the length and the width:

The area is the product of the dimensions:

So, the system is
