Answer:
![y=-222](https://tex.z-dn.net/?f=y%3D-222)
Step-by-step explanation:
When "y varies directly with x" this means that:
![y=k\times x](https://tex.z-dn.net/?f=y%3Dk%5Ctimes%20x)
where k is a number we need to find out (called the constant of proportionality if you care about that).
We can figure out what k is because they tell us when y= -252, x=84. Substituting those values into our equation we get:
![-252 = k \times 84](https://tex.z-dn.net/?f=-252%20%3D%20k%20%5Ctimes%2084)
and therefore:
.
So our equation or formula between y and x is:
.
So when x = 74, then:
![y=-3 \times 74 = -222](https://tex.z-dn.net/?f=y%3D-3%20%5Ctimes%2074%20%3D%20-222)
So you do 7:30 hours is 450 minutes so 82.50/ 450 then times that by 60 and it's 11. so you are paid 11 dollars an hour.
Answer is C => 4(80+20)-12 => 4(100)-12 =>400-12 => 388
You have to combine like terms and solve so the x’s and y’s Multiply together to each other and the 8 will be at the answer:
2x times 3x=6x 5y times 4y=20y and then you factor in 8 to the new expression so: 6x20y8
