Help me PLEAS AND QUICKKK Charles bought a box of fruit that contain only oranges and tangerines there were five oranges for every three tangerines in the box there were 20 oranges in the box which of the following proportion can be used to find X the number of the tangerines in the box A. 5/8 = x/20 B. 5/8 = 20/x C. 5/3 = x/20 D. 5/3 = 20/x

D

Step-by-step explanation:

Oranges in box : 20

Tangerines in box : x

5/3 = 20/X

if you need , reply with more info. u.

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
