x - 18 = 29
x = 47
3q + 13 = 40
q = 9
You and your friend buy tacos. He has 19 tacos, which is 8 more than you had. Write an equation that represents this, and find how many tacos you had.
t + 8 = 19
t = 11
x + y = z
Solve for x
x = -y + z
2(x + 3) = 8
x = 1
4j = 120
j = 30
g/2 - 12 = 1
g = 26
Jonas buys a snickers bar for $5 and 4 KitKats for his friends. In total, he spent 29 dollars. Write an equation, and find the price of a KitKat
4k + 5 = 29
k = 6
x + k - f = 90
Solve for k
k = 90 - x + f
4(2x + 9) = 52
x = 2
j + 19.6 = 13
j = -6.6
w = 42
How old is Mr. Haas if 400 reduced by 2 times my age is 350
400 - 2a = 350
a = 25
v = lwh
Solve for h
h = v/lw
5x + 2 + 3x = 42
x = 5
k / 13.4 = 15
k = 201
(1/4)f + 40 = 4
f = -144
Imani spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for $4. What is her weekly allowance if she ended with $12
1/2m + 4 = 12
m = 16
v = a + bc
Solve for c
c = (v - a)/b
-3(2x - 7) = 12
x = 3/2 OR 1.5
t + 1/3 = 7/12
t = 1/4 OR 3/12
12.9r + 16.3 = 56.29
r = 3.1
Anna bought 8 tetras and 2 rainbow fish for her aquarium. The rainbow fish cost $6 more than the tetras. She paid a total of $37. Write and solve an equation to represent how much each tetra fish costs
8t + 2(t+8) = 37
t = 2.1
lw = v/h
Solve for h
(This is probably the hardest question)
h = v/lw
1/2(x + 4) = 4/5
x = -12/5 OR -2.4
