Use the property of parallelograms to solve for the missing variable

x = 16, y = 6

Step-by-step explanation:

Using the property of parallelogram; the parallel sides are equal in length

We have it that;

3x -7 = 2x + 9

3x - 2x = 9 + 7

x = 16

For the other side;

5y = 2y + 18

5y -2y = 18

3y = 18

y = 18/3

y = 6

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
