The answer is C.
-- multiply both sides by 10. 3/8 * 10 = x.
-- 3*10/8 = x
-- 30/8 = 15/4 = 3 3/4 =>
-- x = 3.75.

C. Cross multiply 3 x 10 = 30, 8 x X = 8X, 8X = 30 then divide 8X and 30 by 8. Hence, X = 3.75

3/8 = x/10, multiply both sides by 10 so you will have 30/8 = x, and 30/8 = 3.75 so your answer is C.

3/8=x/10
=>3*10=8*x (by cross multiplication)
=>30=8x
=>x=30/8=3.75

cross multiply so you get 8x=30, then divide both sides by 8 (8x/8=30/8) then the 8's cross out leaving you with just x=3.75
so the answer is C. 3.75

The made of the potential (x+ 3 and eight ) equals the made of the extremes ( 4 and 10 ). 4 circumstances 10 = 40 = (x + 3) circumstances 8 40 = 8x+ 24......40 - 24 = 8x......sixteen = 8x......sixteen/8 = x = 2 Your welcome!
