The skateboard would cost d-2h dollars because when the amount of money for both of the helmets is subtracted from the total dollar amount, then that leaves the amount that was paid for the skateboard since Timmy did not buy anything else.
I believe you are right, it is C
If you go through each option, it would be correct.
-5(7) = -35 + 3 = -32
-3(7) = -21 + 3 = -18
-1(7) = -7 + 3 = -4
6(7) = 42 + 3 = 45
7(7) = 49 + 3 = 52
So the equation y= 7x+3, as you selected would be correct.
Please correct me if I am wrong and have a good day!
Given the following equation
![4x+y=8](https://tex.z-dn.net/?f=4x%2By%3D8)
We want to write an equivalent equation. When you do the same operation on both sides of an equation, the equal sign stays valid. Let's say we multiply both sides by two
![2\cdot(4x+y)=2\cdot(8)\Rightarrow8x+2y=16](https://tex.z-dn.net/?f=2%5Ccdot%284x%2By%29%3D2%5Ccdot%288%29%5CRightarrow8x%2B2y%3D16)
This equation is equivalent to the first one. Instead, we could've add three to both sides and then subtract 'y' from both sides.
![4x+y+3-y=8+3-y\Rightarrow4x+3=11-y](https://tex.z-dn.net/?f=4x%2By%2B3-y%3D8%2B3-y%5CRightarrow4x%2B3%3D11-y)
And all of those equations are equivalent.
