Sure, I'd be happy to help you with your Equations and Inequalities Unit Test.
Let's go through each question one by one and solve them:
1. Solve the equation: -9v - 5 = -95
To solve this equation, we need to isolate the variable v.
Step 1: Add 5 to both sides of the equation.
-9v - 5 + 5 = -95 + 5
-9v = -90
Step 2: Divide both sides of the equation by -9.
-9v / -9 = -90 / -9
v = 10
So, the answer is C. 10.
2. Solve the equation: x/4 - 5 = -8
To solve this equation, we need to isolate the variable x.
Step 1: Add 5 to both sides of the equation.
x/4 - 5 + 5 = -8 + 5
x/4 = -3
Step 2: Multiply both sides of the equation by 4.
4 * (x/4) = -3 * 4
x = -12
So, the answer is D. -12.
3. Solve the equation: p/5 + 6 = 10
To solve this equation, we need to isolate the variable p.
Step 1: Subtract 6 from both sides of the equation.
p/5 + 6 - 6 = 10 - 6
p/5 = 4
Step 2: Multiply both sides of the equation by 5.
5 * (p/5) = 4 * 5
p = 20
So, the answer is C. 20.
4. Solve the equation: -2(m - 30) = -6m
To solve this equation, we need to simplify and isolate the variable m.
Step 1: Distribute the -2 to the terms inside the parentheses.
-2m + 60 = -6m
Step 2: Combine like terms by adding 6m to both sides of the equation.
-2m + 60 + 6m = -6m + 6m
4m + 60 = 0
Step 3: Subtract 60 from both sides of the equation.
4m + 60 - 60 = 0 - 60
4m = -60
Step 4: Divide both sides of the equation by 4.
4m / 4 = -60 / 4
m = -15
So, the answer is A. -15.
5. Solve the equation: 3n + 2 = 8 + 2n
To solve this equation, we need to isolate the variable n.
Step 1: Subtract 2n from both sides of the equation.
3n - 2n + 2 = 8 + 2n - 2n
n + 2 = 8
Step 2: Subtract 2 from both sides of the equation.
n + 2 - 2 = 8 - 2
n = 6
So, the answer is D. 6.
6. Simplify the expression: -4 - 5(w + 8)
To simplify this expression, we need to multiply the -5 by each term inside the parentheses.
-4 - 5w - 40
Simplifying further, we get:
-5w - 44
So, the answer is A. -5w - 44.
I hope this helps! Let me know if you have any more questions.
