Answer:
54
Step-by-step explanation:
2x+2=3x-52
subtract 2 from both sides
2x=3x-54
x=54
Answer:
has 25, wants 130, so he needs to save (130-25)= 105.
105/7= 15 weeks
25+7w= 130
Answer:
(12, 3.2) would be the max amount of gas he could buy. (11.25, 3) for an even gallon amount.
Step-by-step explanation:
First arrange all of the distances as fractions
1 2/3 miles = 5/3
1 3/4 miles = 7/4
Now you have to make them common denominators
5/3 = 20/12
7/4 = 21/12
Now add them
20/12 + 21/12 = 41/12 miles
Now to find the distance in the last 1/2 hour.
41/12 x 1/4 = 41/48 miles
Now we have to add them, but first make them have common denominators.
41/12 = 164/48
Now to add it all up.
164/48 + 41/48 = 205/48 miles
Because the 2 lines are parallel, (5x+5) + 115 need to equal 180.
Solving for X:
5x+5 +115 = 180
5x + 120 = 180
Subtract 120 from each side:
5x = 60
Divide both sides by 5
x= 60/5
X = 12
