Division property of equality, because you have to divide 8x and 80 by 10
(5x2+10^3) +10+7 -> (10+1000) + 17 -> (1010) x 17 = 17,170
4 km = 4000 m = 400000 cm
Scale: 3:400000
answer: 3:400000
Y=(3/4)^x represents exponential decay since 3/4 is less than one, so y will become increasing smaller as the exponent increases
