1. To solve the equation -2v - 7 = -23, you can begin by isolating the variable v. Start by adding 7 to both sides of the equation:
-2v - 7 + 7 = -23 + 7
-2v = -16
Dividing both sides by -2 gives:
v = -16 / -2
Simplifying,
v = 8
The correct answer is B) 8.
4. To solve the equation -2(m - 30) = -6m, start by distributing the -2 to each term inside the parentheses:
-2m + 60 = -6m
Add 6m to both sides to collect all the variables on one side:
4m + 60 = 0
Subtract 60 from both sides:
4m = -60
Divide both sides by 4:
m = -60 / 4
Simplifying,
m = -15
The correct answer is A) -15.
5. To solve the equation 3n + 2 = 8 + 2n, collect all the terms containing n on one side of the equation:
3n - 2n = 8 - 2
Simplifying,
n = 6
The correct answer is D) 6.
6. To simplify the expression -6 - 7(c + 10), distribute the -7 to each term inside the parentheses:
-6 - 7c - 70
Combine like terms:
-76 - 7c
The correct answer is B) -76 - 7c.
7. To solve the equation 6(x - 2) = 36, start by distributing the 6 to each term inside the parentheses:
6x - 12 = 36
Add 12 to both sides:
6x = 48
Divide both sides by 6:
x = 8
The correct answer is D) 8.
8. To solve the inequality p + 4 < -24, start by subtracting 4 from both sides:
p < -28
The correct answer is C) p < -28.
10. To solve the inequality -8x > -64, divide both sides by -8. Remember to flip the inequality sign:
x < 8
The correct answer is A) x < 8.
