Answer: 4. ?=18

5. x = 6

Explanation:

First put the length in ratio form:

4. 54:? and 24:8 ==> 54:?=24:8

Now put the ratios in division form:

54/? = 24/8

54/? = 3 ==> simplify

? * 54/? = 3*? ==> multiply by ? on both sides to remove denominator

54 = 3?

54/3 = 3?/3 ==> divide by 3 on each sides to solve for ?

?=18 ==> simplify

5. (6x-1):14 and 15:6

(6x-1)/14 = 15/6

14*(6x-1)/14 = 14 * 15/6 ==> multiply by 14 on both sides to isolate x

6x-1 = 210/6

6x-1 = 35 ==> simplify

6x-1+1 = 35+1 ==> add 1 on both sides to isolate x

6x = 36

6x/6 = 36/6 ==> divide by 6 on both sides to isolate x

x = 6 ==> simplify
