Depends how you were taught to solve it but if it were me I’d choose B) minimum value at -6
On this, you would want to multiply the first by 1.12. So then 17.4 x 1.12= 19.488. when rounded, it equals 19.5 miles.
81 * 1 / 27^y = 9 ^2y+1
81 * 1 / 9^3y/2 = 9 ^ 2y+1
9^3y/2 * 9 ^ (2y+1) = 81
9 ^ ( 3y/2 + 2y + 1) = 81 = 9^2
3y/2 + 2y + 1 = 2
7y/2 = 2 -1 = 1
7y = 2
y = 2/7 answer
78 there 12 inches in a foot so 12 * 7 = 72 plus 1/2 a foot witch is 6 inches equals 78 inches
