Answer C. 6 hours

Step-by-step explanation:

12/2=6  36/6=6 $6 per hour

C. 6 hours

Step-by-step explanation:

Roy worked for 2 hours and earned $12.

First you want to know how much money he made in one hour. So you divide 12 by 2.

12 ÷ 2 = $6 per hour

Now you wanna know how many hours must he work at the same rate to earn $36.

$6 × 6hours = 36

So the answer is C. 6 hours

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

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!
