How does 3x = 4(x-2.25) = 9. wherethe hell is everyone getting a at a bargain store, tanya bought three items that each cost the same amount. tony bought four items that each cost the same amount, but each was $2.25 less then the items that tanya bought. both tanya and tony paid the same amount of money. what was the individual cost of each person's items?

Step-by-step explanation:

Here is how to get 9:

3x = 4(x - 2.25)

Solve 4(x - 2.25)

3x = 4x - 9

Move the variable to the left side and change it's sign

3x - 4x = -9

Combine like terms

-x = -9

change the signs

x = 9

There ya go! I hope this isn't too confusing!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
