At a bookstore, the price of two notebooks plus a $40 backpack is the same as the price
of 10 notebooks. Which equation could be
used to find the price of each notebook?
A. 2x = 10x + 40
B. 2x + 40 = 10x
C. 40 = 2x + 10x
D. 2x - 40 = 10x
Need help

B. 2x + 40 = 10x

Step-by-step explanation:

Notebook price = x

The price of 2 notebooks = 2x

Price of a backpack = 40

Price of 10 notebooks = 10x

So, the equation would be 2x + 40 = 10x.

Hence, the answer is choice C.

the answer is b.)

< 1=< 2

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
