E(x)=840-52.5x let e(x) be the elevation, in meters, of a cable car from the ground, x minutes after it begins descending from the top of a hill. since e(14) = , the elevation of the cable car will be meters from the ground minutes after it begins descending from the top of the hill.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

the answer is 489

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
