Answer:

Each book costs about $22.06

Step-by-step explanation:

[] We can set up a proportion, and then use cross-multiplying to solve:

\frac{7books}{154.40dollars} =\frac{1book}{x}

7x = $154.4

x = 22.05714

x ≈ $22.06

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

How is the expression (5 + y) ⋅8 described by its factors and terms?
ICE Princess25 [194]
Answer: Choice D
It has two factors and the factor (5+y) has two terms

=========================================================
Explanation:

(5+y)*8 is in the form P*Q where
P = 5+y
Q = 8
So we have two factors multiplied together. A factor is simply a number that helps multiply to a larger one. Another example: 14 has the factors 7 and 2 because 7*2 = 14

The factor 5+y has two terms which are 5 and y. The terms are separated by a plus sign. If you had something like 5-y, then you can write it as 5+(-y) and you'd still have two terms.

Hey!

-----------------------------------------------

PEMDAS stands for the steps in solving an equation.

P - Parenthesis

E - Exponent's

M - Multiply

D - Divide

A - Addition

S - Subtract

-----------------------------------------------

Expression:

= 6 × 5 + 3 × 8

Multiply first since its the first step in this equation:

= (6 × 5) + (3 × 8)

Simplify:

= 30 + 24

Answer:

= 54

-----------------------------------------------
