Find the the value f y in the parallelogram.

a.2
b. 1.5
c. 0.5
d. 7.5

B

Step-by-step explanation:

All parallelograms have diagonals which bisect each other. This means the diagonals intersect and create equal lengths.

5y = 3x + 6

8x - 2 = 4x

Solve for x using 8x - 2 = 4x. Then substitute x into the other equation.

8x - 2 = 4x

-2 = -4x

1/2 = x

Substitute x = 1/2.

5y = 3(1/2) + 6

5y = 3/2 + 6

5y = 3/2 + 12/2

5y = 15/2

y = 15/10

y = 3/2 or 1.5

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
