Mariah bought 5 shirts that each cost the same amount and a pair of jeans that cost $30. She spent a total of $150 at the store. Write an equation to determine the cost of each shirt.

150-30=5x

Step-by-step explanation:

If the total is $150 and a pair of jeans is $30, then you'd subtract them. Since you have to find out how much each shirt is, you'd put 5x on the other side of the equal sign. Then solve for X.

Hope this helps!

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

here try this one

3a-24=0

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
