Answer:

x= 3

Step-by-step explanation:

Given data

Ratio= 5:2:x

Combined ratio= 5+2+x

                        = 7+x

Total amount of money= $15000

Let us apply the part to all method

Hence for Matthew whose share = $7500

5/7+x=  7500/15000

Cross multiply we have

7500*(7+x)= 15000*5

52500+7500x= 75000

Collect like terms we have

7500x= 75000-52500

7500x=22500

x= 22500/7500

x=3

Hence the value of x= 3

Lf g(x) = x3 - 5 and h(x) = 2x - 2, find g(h(3)).
White raven [17]

Answer: g(h(3)) = 59

Step-by-step explanation:

Well if its x^3 I assume it is because you wrote other coefficients before the variable.

2(3) - 2 = 6-2 = 4

So 4 is the x input for h(x)

4^3 -5 = 64-5 = 59
