brenda and jessica are selling wrapping paper for a school fundraiser. customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. brenda sold 2 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $41. jessica sold 7 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $106. write a system of equations that could be used to find the cost of the wrapping papers.

a system of equations that could be used to find the cost of the wrapping papers are

2x + y = 41

7x + y = 106

Step-by-step explanation:

Let x represent the cost of one roll of plain wrapping paper.

Let y represent the cost of one roll of holiday wrapping paper.

Brenda sold 2 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $41. This can be expressed as

2x + y = 41

Jessica sold 7 rolls of plain wrapping paper and 1 roll of holiday wrapping paper for a total of $106. This can be expressed as

7x + y = 106

(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

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
