The three children are x, 2x, and x+5
So set up an equation: x+2x+x+5=57
Solve: 4x=52 so x=13
So the ages are...

13, 18, 26

Check: 13+18+26=57

Artist 52 [7]

Answer:

Step-by-step explanation:

Given:

  • The shipping charge for the entire order is five dollars
  • $10 for each hat
  • the total of the college order is less than $120  

Let x is the number of hats the coach other, we have the inequality

5 + 10x < 120

<=> 10x < 115

<=> x < 115/10 = 11.5

So the maxinum hats the coach can other is 15.

The tables represent the functions f(x) and g(x).
dolphi86 [110]

A function assigns the values. The correct option is C, x=-6.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

A.) When the value of x is -12,

f(-12) = 2/3(-12) + 7 = -1

g(-12) = 2(-12) + 15 = -9

B.) When the value of x is -9,

f(-9) = 2/3(-9) + 7 = 1

g(-9) = 2(-9) + 15 = -3

C.) When the value of x is -6,

f(-6) = 2/3(-6) + 7 = 3

g(-6) = 2(-6) + 15 = 3

D.) When the value of x is -3,

f(-9) = 2/3(-3) + 7 = 5

g(-9) = 2(-2) + 15 = 11

Hence, the correct option is C, x=-6.
