Joan spend half of her paycheck going to the movies. she washed the family car and earned 7 dollars. what is her weekly paycheck if she ended up with 18 dollars?

her weekly allowance is $16

Step-by-step explanation:

Let x represent Joan's weekly paycheck.

Joan spent half of her paycheck going to the movies. This means that the total amount that she spent at the movies is x/2. The amount that she is left with would be

x - x/2 = x/2

She washed the family car and earned 7 dollars. This means that the total amount left with her is

x/2 + 7

if she ended with 18 dollars, it means that

x/2 + 7 = 18

x/2 = 18 - 7 = 11

x = 2 × 11 = $22

step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
