Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5
Answer:
39.50
42.50
Step-by-step explanation:
Age of the 2 men = sum of the ages of the 6 men - sum of the ages of the 4 men
Average = sum of ages / total number of men
35 = sum of ages / 6
sum of ages = 35 x6 = 210
32 = sum of ages / 4
32 x 4 = sum of ages
128
210 - 128 = 82
age of the younger man = x
age of the older man = 3 + x
x + 3 + x = 82
2x + 3 = 82
2x = 82 - 3
2x = 79
x = 79/2 = 39.5
older man = 39.5 + 3 = 42.50
