oh sorry 5 was b
You've just made that 100% WRONG.
Hey Damien, try checking your answers by substituting them back in the original
for example
-9(-10) - 5
= 90 - 5
= 85 which is NOT -95
To check if your answers are correct, let's solve each equation step by step:
1. -9x - 5 = -95
Start by adding 5 to both sides to isolate the x term:
-9x = -90
Divide both sides by -9 to solve for x:
x = -90 / -9
x = 10
So the correct answer is C) 10.
2. x/3 - 10 = -12
Start by adding 10 to both sides to isolate the x term:
x/3 = -12 + 10
x/3 = -2
Multiply both sides by 3 to solve for x:
x = -2 * 3
x = -6
So the correct answer is A) -6.
3. d/3 + 10 = -12
Start by subtracting 10 from both sides to isolate the d term:
d/3 = -12 - 10
d/3 = -22
Multiply both sides by 3 to solve for d:
d = -22 * 3
d = -66
So the correct answer is D) -66.
4. 2(2 - 2x) = -3x
Start by distributing 2 to both terms inside the parentheses:
4 - 4x = -3x
Move all terms involving x to one side of the equation:
-4x + 3x = -4
-x = -4
Divide both sides by -1 to solve for x:
x = 4
So the correct answer is B) 4.
5. 2.9n + 1.7 = 3.5 + 2.3n
Start by moving all terms involving n to one side of the equation:
2.9n - 2.3n = 3.5 - 1.7
0.6n = 1.8
Divide both sides by 0.6 to solve for n:
n = 1.8 / 0.6
n = 3
So the correct answer is A) 3.
Based on the solutions above, your correct answers are:
1) C) 10
2) A) -6
3) D) -66
4) B) 4
5) A) 3
