At columbus north high school bookstore, kenzie purchased a math textbook and a novel that cost a total of $56, not including tax. the price of the math textbook, m, is $8 more than 3 times the price of the novel, n. find the price of each book.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
