Question

Given the median and trapezoid MNOP, what is the value of x?

Answer 1

solve for x
1/2 (3x-8 + 7x + 4) = 33

Answer 2

If you add the two bases and divide by 2 you will get the median.

Answer 3

i got this: 1/2 10x - 4 =33 :/

Answer 4

Answer 5

yeah, u just simplify the terms in bracket
1/2 (10x - 4) =33

can u solve for x ?

Answer 6

wait do i divide by 0.5???

Answer 7

first, multiply by 2 to both sides, what u get ?

Answer 8

20x - 8 :/

Answer 9

2 * 1/2 (10x - 4) = 2 *33
10x - 4 = 66, agree ?
