Answer:

Felipe drove the truck for 1.26 miles

Step-by-step explanation:

Given :

Base fee = $14.95

Additional charge for each mile driven = 87 cents

Amount Felipe paid when he returned the truck = $124.57

To Find:

How many miles did he drive the truck =?

Solution:

Let number of miles Felipe drove be X

Then according to the question,

Base fare + 87(number of miles driven) = 124.57

Substituting the known values,

14.95 + 87(x) = 124.57

124.57- 14.95 = 87 x

109.62 = 8x

x = $\frac{109.62}{87}$

x = 1.26

Answer:

$\boxed{\sf \ \ 9x^2-18x-7 \ \ divided \ by \ (3x+1) \ is \ (3x-7) \ }$

Step-by-step explanation:

Hello,

let's find a and b reals so that

$9x^2-18x-7=(3x+1)(ax+b)$

$(3x+1)(ax+b)=3ax^2+(3b+a)x+b$

we identify the terms in $x^2$

9 = 3a

we identify the terms in x

-18 = 3b + a

we identify the constant terms

-7 = b

so ti goes with a = 9/3 = 3, b = -7

so we can write

$9x^2-18x-7=(3x+1)(3x-7)$

so $9x^2-18x-7 \ divided \ by \ (3x+1) \ is \ (3x-7)$

hope this helps
