MACHO ATE 125 HOT DOGS OVER A FIVE DAY PERIOD. EACH DAY HE AT SEVEN MORE HOT DOGS THAN ON THE PREVIOUS DAY. HOW MANY HOT DOGS DID HE EAT ON THE FIRST DAY?

MATH 
Reiny,
first day > x
2nd day > x+7
etc
x + x+7 + x+14 + x+21 + x+28 = 125
5x = 55
x = 11 
MATH 
Henry,
x = (x+7) + (x+14) + (x+21) + (x+28) =
125,
5x + 70 = 125,
5x = 125  70 = 55,
x = 11. 
MATH 
Nicole,
I agree 100% with that answer and I understand all of it besides:
5x + 70 = 125
please help 
MATH 
Henry,
X + (X + 7) + (X + 14) + (X + 21) + (X + 28) = 125.
X + X + X + X + X = 5X.
7 + 14 + 21 + 28 = 70.
5X + 70 = 125
5X = 125  70 = 55
X = 11.
I'm glad i could help.
