A gym charges a $10 membership fee plus $25 per month. Nate has paid a total of $85 so far to the gym.
Write an equation to represent the situation. Let m represent the number of months.
Answers may vary;
25m + 10 = 85
25m = 75
m = 3
Solve for y
6y + 18 = 42
y = 4
Solve for m
15 - 3m = 63
m = -16
Explain the mistake in words AND solve it correctly.
-5x + 9 = -1
-9=-9
-5x = -10
+5 = +5
x=-5
The mistake is instead of dividing by -5, they added 5 to both sides.
x = 2
Solve for f
-4f + 12 = -8
f = 5
Solve for k
5 = -3 + k/7
k = 56
Easton bought 6 boxes of cereal and 3 gallons of milk for a total cost of $29.85. Each box of cereal costs $3.40. Enter the cost, in dollars, of 1 gallon of milk.
3g + 6(3.40) = 29.85
1 Gallon of Milk Cost: $3.15
Solve for x
x/-5 + 11 = 16
x = -25
Solve for x
(-2x+9)/7=5
x = -13
Jess and her friends went to the movies. All four people bought 1 ticket and 1 soda. Each soda cost $3.50. Lisa and her friends spent a total of spend a total of $54.40.
Write an equation that models the situation with t, the cost of 1 ticket.
Answers may vary;
4t + 14 = 54.40
4t + 3.50(4) = 54.40
4t = 40.40
t = 10.10
Solve for k
-7=k/3 -2
k = -15
Solve for g
(4g)/5 -2 =-6
g = -5
