2(3x-5) + 2(-2x+10)
6x-10 + -4x+ 20
=2x+ 10
Answer:
8 months
Step-by-step explanation:
12/3 = 4, 1/3 is 4 so 1/3 + 1/3 = 2/3 or 8
Step-by-step explanation:
2x + 100 = 90
x = -5
Angle A = 45 - 5 = 40.
54=.9x Solve for x. x=54/.9=60
Answer:
13.5 = 9.5 + x
x=4
Step-by-step explanation:
In this problem, the price of the baseball cap, which is $9.50, and a baseball, whose price is unknown (and therefore must be the variable), total $13.50. So, to set up the equation add the two prices and set them equal to the total, 9.5+x=13.5.
Then, using the subtraction property of equality subtract 9.5 from both sides. This means x=4, so the baseball cost 4 dollars.
