Looks like somebody has a lot of work ahead of them
Sure, I can help you with that!
1. -2v - 7 = -23
To solve this equation, you need to isolate the variable v.
Adding 7 to both sides of the equation, we get:
-2v = -16
Next, divide both sides of the equation by -2:
v = 8
So the correct answer is B) 8.
4. -2(m - 30) = -6m
To solve this equation, distribute the -2 to terms inside the parentheses:
-2m + 60 = -6m
Next, simplify the equation by adding 6m to both sides:
4m + 60 = 0
Subtracting 60 from both sides, we get:
4m = -60
Finally, divide both sides of the equation by 4:
m = -15
So the correct answer is A) -15.
5. 3n + 2 = 8 + 2n
To solve this equation, move all the terms containing n together on one side:
3n - 2n = 8 - 2
Combine like terms:
n = 6
So the correct answer is D) 6.
6. Simplify the expression: -6 - 7(c + 10)
To simplify this expression, distribute the -7 to terms inside the parentheses:
-6 - 7c - 70
Combine like terms:
-76 - 7c
So the correct answer is B) -76 - 7c.
7. 6(x - 2) = 36
To solve this equation, distribute the 6 to terms inside the parentheses:
6x - 12 = 36
Next, simplify the equation by adding 12 to both sides:
6x = 48
Finally, divide both sides of the equation by 6:
x = 8
So the correct answer is D) 8.
8. Solve the inequality: p + 4 < -24
To solve this inequality, subtract 4 from both sides of the inequality:
p < -28
So the correct answer is C) p < -28.
10. -8x > -64
To solve this inequality, divide both sides of the inequality by -8. Remember that dividing by a negative number flips the inequality sign.
x < 8
So the correct answer is A) x < 8.
I hope this helps! Let me know if you have any other questions.
