y = quantity, for example:
I want to buy 1 bracelet =
1×7 = 7 + 1 = 8$ per bracelet
Two equivalent fractions equations are
r + 6
6 + r <span />
Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55
