Answer:
n is equal to 26
Step-by-step explanation:
Equation: n+ n + (n+2) +(n+2) = 108
so: 2n + 2(n+2) = 108
2n + 2n + 4 = 108
4n + 4 = 108
4n = 108 - 4
4n = 104
n = 104/4
n = 26
Answer:
Emily: 13, Peter: 9, Joshua: 18
Step-by-step explanation:
Emily = x
Peter = Emily - 4 = x - 4
Joshua = 2(Peter) = 2(x - 4)
Total = 40 = Emily + Peter + Joshua = (x) + (x - 4) + 2(x - 4)
40 = 2x - 4 + 2x -8
40 = 4x - 4 - 8
40 = 4x - 12
52 = 4x
x = 13
Emily = 13
Peter = 13 - 4 = 9
Joshua = 2(13 - 4) = 2(9) = 18
13 + 9 +18 = 40
