Which of the following statements should come first in the paragraph proof for the problem shown below? Given: 150 = 15x + 90
Prove: x = 4

A. The equation 150 = 15x + 90 is given in the problem

B. Simplify the equation to 150 = 15x

C. Isolate the variable by subtracting 90 from both sides

D. The solution x = 4 is found by simplifying

the answer is 5/3x+7/5y+7

a

b

d

step-by-step explanation:

the anwser is d) 75°

step-by-step explanation:

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.

sorry if it was confusing!
