Answer: $28-$33
Step-by-step explanation: Call the cost per pair x. She buys the first pair full price, so x, then 2 dollars off, so x-2, and 2 dollars off, so x-2, adding them up you get 3x-4= total money spent. Sinze this ranges from 80-95 solve equations and you get 28 and 33 respectively.
Answer:
3/2 - 4 = y
Step-by-step explanation:
2y - 3x = -8 original problem
2y -3x + 8 = 0 addition property of equality
-3x + 8 = -2y subtraction property of equality
3/2x - 4 = y division property of equality
Answer:
-7-√15
Step-by-step explanation:
First move the constant to the right hand side and change it's sign
x^2+14x=-34
Then add (14/2)^2 or 7^2 to both sides
x^2+14x+49=-34+49
Then factor the expression
(x+7)^2=-34+49
Then solve (x+7)^2=15
You should get:
x=-√15-7
or
x=√15-7
