Ahmad made $105 for 7 hours at the same rate how many would he have to work to make $255?

Answer

15 hours

Step-by-step explanation:

If he makes $105 dollers in 7 hours then he makes $15 an hour because 105 divided by 7 is 105. you have to keep multipling by 15 untell you get $255. and 15 x 15 = 255

B. (-3, 0)

Step-by-step explanation:

y = x + 3

2x + y = -6

substitute y = x+3

2x + x +  3 = -6

combine like terms

3x + 3 = -6

subtract 3 from both sides

3x = -9

divide both sides by 3

x = -3

substitute the value ox x into the original equation

2x + y = -6

2(-3) + y = -6

-6 + y = -6

+6          +6

y = 0

hope this helps and have a great  day
