X=2
2x-3=-x+3
add three to both sides
add 1x to each side
should be left with 3x=6
divide both sides by 3 to get x alone
your answer then is x=2
A variable with a fraction exponent can be rewritten using a radical.
The equations would be A. radical equation
3x8 is 24 plus 4 is 28
7x1 is 7 plus 2 is 9
9+28 is 37
KP - break this one down to three parts: Total cost of shirts, total cost of shirts and the skirt, and then including tax.
3 T-shirts for $25.67 each would be 3 * 25.67 = 77.01
Shirts and skirt would be 77.01 + 23.55 = 100.56
Tax can be found quite a few different ways, the easiest of which would be multiplication.
8% = .08
100.56 (total cost of clothes) * .08 (tax) = $8.05
Now just add tax and total cost of the clothes. Because of rounding, our answer might be slightly different but that's okay because it's multiple choice and only 1 answer makes sense!
