What is -3x+13=16 help me with each step.
hoa [83]

-3x+13=16

Move +13 to the other side. Sign changes from +13 to -13.

-3x+13-13=16-13

-3x=16-13

-3x=3

Divide by -3 for both sides.

-3/-3x=3/-3

Cross out -3 and -3, divide by -3, then becomes 1*1*x=x

x=-1

Answer: x=-1

a skateboard company is putting together boards and wheels to make skateboards. the company has a box of 36 boards. they need 4
vodka [1.7K]
If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144.  That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2.  So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.
