Integers
5 + (-9) =
-4
-5/4 + 1/8 =
-9/8
Combine like terms. Simplify completely.
5x − 12 + 7x + 3
12x - 9
-4x +12 = 8
x = 1
What is the value of:
3 (2x − 1) when x = 4?
21
-8 - (-5) =
-3
-7/8 - 3/4 =
-13/8
Use the distributive property.
4(2x - 3y - 1/4)
8x - 12y - 1
-3x - 6 = 21
x = -9
Taylor has at least 12 markers in their collection.
Write the inequality and then show all possible numbers of markers, m, on the number line.
m ≥ 12
27 ÷ (-9) =
-3
5/6 ⋅ (-2/3)
-10/18
-5/9
Use the distributive property.
-6(3y - 4x - 2)
-18y +24x +12
A fruit smoothie has 450 calories. The yogurt has 150 calories, and there are 5 scoops of fruit.
Each scoop has the same number of calories, and there are no other ingredients.
Write an equation for the scenario.
What does x represent?
How many calories are in each scoop of fruit?
450 = 150 + 5x
x is the number of calories in each scoop of fruit.
x = 60
Solve the inequality and graph.
m − 7 ≤ −10
m ≤ -3
What does a equal?
7 ⋅ (-5) = a
-35
5/6 ÷ (-1/3) =
-15/6
-5/2
Simplify the expression
6x + 15 − 4 (x + 3)
2x + 3
Solve for x.
−8 (x − 2) = −48
x = 8
Use the distributive property.
1/4 (16x - 12y - 8)
4x - 3y - 2
