Answer:
Combine like terms
Step-by-step explanation:
3x + 6 = 10 + 3x + 4x
Combine like terms
3x + 6 = 10 + 7x
Subtract 3x from each side
3x-3x + 6 = 10 + 7x -3x
6 = 10 +4x
Subtract 10 from each side
6-10 = 10+4x-10
-4 = 4x
Divide by 4
-4/4 = 4x/4
-1 =x
i'm not sure how much the lanes are, so i'm gonna list the prices of pairs of shoes so you can just add the price of the lanes and find the answer:
1 pair - 2.95
2 pairs - 5.90

6 pairs - 17.70
7 pairs - 20.65

(thats the highest amount of shoes he could get)
Answer:
x = -10
y = 13
Step-by-step explanation:
-3x + 2y = 56
-5x - 2y = 24
__________ +
-8x____ = 80
x______= 80/-8
______x = -10
-3x + 2y = 56
-3(-10) + 2y = 56
30 + 2y = 56
2y = 56 - 30
2y = 26
y = 26/2
y = 13
Answer:
to find the area of a parallelogram you do base X height
Answer:
<h3>2.5hrs</h3>
Step-by-step explanation:
Given the equation 250 + 200h = 300 + 180h, we are to find the amount of credit hours will a student have to take for the two tuition costs to be equal, to do that we need to make h the subject of the formula:
250 + 200h = 300 + 180h
collect like terms
200h - 180h = 300-250
20h = 50
2h = 5
Divide both sides by 2:
2h/2 = 5/2
h = 5/2
h = 2.5hr
Hence the student will take 2.5hr.
