Step-by-step explanation:
2,547 / 4 = 636.75 There are 636 stacks with 3 tires left over.
4 tires at 65 each = $260
4 tires at 2 for 120 = $240
He should buy 2 sets of 2 tires for $120 and save $20.
0.00305 and 8920000...if the exponents are negative 3 and 6
X = adult
y = children
53(x+y=431)
53x +24y = 15390$
53x+53y = 22,843
subtract from
53x+24y = 15,390
29y = 7,453$
y = 257
53x + 24 (257) = 15,390
53x + 6,168 = 15,390
53x = 9,222
x = 174
3x + 4(x + 1) = 67
7x + 4 = 67
7x = 67-4 = 63
x = 9
The smaller integer is 9.
