Solve for x: 5x + 4 = 24
x = 4
Simplify this expression: (2/5)p + (7/10)p
(11/10)p
Sienna drove x miles per hour for 3 hours, and (2x - 60) miles per hour for the next 4 hours. Express the total distance Sienna traveled in terms of x.
11x - 240
The common multiple of the denominators of two or more fractions that has the least value is called what?
Least Common Denominator (LCD)
Insert one set of parenthesis to make this equation true: 24 - 3 x 32 - 6 = 7
24 - 3 x (32 - 6) = 7
Solve for y: 9y + 4 = 13y - 6
y = 2.5
Simplify this expression: 0.8a + 3.9b + 1.8a
2.6a + 3.9b

33 - 6 x 2 + 24 = ?
31
Solve for z: 0.6(z + 3) = 3z
z = .75 or z = 3/4
Expand and simplify this expression: -2(4m + 1) - m
-9m - 2
Eliza is in charge of ordering new uniforms for her team. She has $400 to spend. Each uniform cost $29 and it costs $42 for shipping for all of the uniforms. Write and solve an inequality to determine how many uniforms (u) can Eliza order?
29u + 42 is less than or equal to 400.
u = 12
In the equation y = kx, k is called what?
k is the constant of proportionality.
42 - 3(6 + (-2)(10 - (-2))) = ?
70
Solve for t: (1/4)(t - 4) - (3/4)t = 3
t = -8
Expand and simplify this expression with two variables: -7(y + 2t) - 3(y - t)
-10y - 11t
Anastasia walks 3 miles in 45 minutes. Given that her distance (d) is directly proportional to the time (t) she walks, find the constant of proportionality.
d = kt so k = 3/45 or 1/15.
Two angles which share a vertex and a side, but no interior points, are called what type of angles?
Adjacent angles.
Insert two sets of parenthesis to make this statement true: 4 x 42 + 10 - 10 x 52 - 20 = 54
4 x (42 - 10) - 10 x (52 - 20) = 54
Solve for w: 3w - 14 = 3w + 3
No solution!
