2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
(X +(x + 4) +3x)/3 = (5x +4)/3
Add the ages together and divide by the number of people to get the mean.
Answer:
88
Step-by-step explanation:
33 plus 55
1.) Distribute the negative to what is in the parenthesis
2x - 3 + x > x + 1
1.) Simplify
Distribute the negative to what is in the parenthesis:
2x - 3 + x > x + 1
Solve for x
3x - 3 > x + 1
2x - 3 > 1
2x > 4
X > 2
2.) We know that x is everything thing greater than 2. The answer would be D because the highlighted part (x) is everything that is greater than 2
