Pythagorean Theorem
3*3+8*8=x*x
9+64=x*x
73=x*x
x=√73≈8.5
Answer:
x=5
Step-by-step explanation:
4x + 8 = 28,
it's rather straight forward,
you would subtract 8 from the left side,
doing the same on the right.
now you have
4x = 20
x= 20/4
x=5
hope this helps.
Answer:
Last year's price was $12.50.
Step-by-step explanation:
We'll use the variable x to represent last year's price. First, we have to set up an equation:
.60x + x = 13.25
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
.06x + x = 13.25
1.06x=13.25
1.06 r 1 .06 = 13.25 1.06
=$12.50
Last year's price was $12.50.
