On monday, lyn johnson worked for 3 1/4 hours. tuesday thursday, she worked for 4 1/3 hours each day. on friday, she worked for 6 1/2 hours. how many hours total did she work during the five days?

22  3/4 hours

Step-by-step explanation:

monday + tuesday + wednesday + thursday + friday

3 1/4 + 4 1/3 + 4 1/3 + 4 1/3 + 6 1/2

the common denominator is 12

3 1/4 *3/3  = 3 3 /12

4 1/3 * 4/4 = 3 4/12

6 1/2 * 6/6 = 6 6/12

3 3 /12 + 4 4/12 + 4 4/12 + 4 4/12 +6 6/12 =

(3+4+4+4+6) + (3 +4+4+4+6)/12

21 +(21/12)  we can simplify 21 /12

21 + 12/12 + 9/12

21 + 1 + 9/12

22 + 9/12  we can simplify 9/12 by dividing top and bottom by 3

22  3/4

(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

your answer is the frist one
