Simplify the expression.
Subtract 7x-7 from 5x + 2.

2x – 9

Step-by-step explanation:

(7x – 7) – (5x + 2) →

(7x – 7) + -(5x + 2) →

(7x – 7) – 5x – 2 →

7x – 7 – 5x – 2 →

(7x – 5x) + (-7 – 2) →

(2x) + (-9) →

2x – 9

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
