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, Sunday, September 5, 2010 at 9:50pm
first day > x
2nd day > x+7
etc
x + x+7 + x+14 + x+21 + x+28 = 125
5x = 55
x = 11

MATH  Henry, Sunday, September 5, 2010 at 10:04pm
x = (x+7) + (x+14) + (x+21) + (x+28) =
125,
5x + 70 = 125,
5x = 125  70 = 55,
x = 11.

I agree 100% with that answer and I understand all of it besides:
5x + 70 = 125
please help

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.
