Pl math pl last question

This question is based on parallel lines proportionality that states if three or more lines intersect two traversals, then they cut the traversals proportionally.

In this case, the formula becomes:

The value of x = 10

To find the proportions or DE and EF,

DE = 2x = 2*10=20

EF = 3x-5 = 30-5 = 25

If we find DE/EF, it becomes 20/25 or 4/5

the answer would be c:   ax + b = ax + c

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
