Please help us!!! I need this test too!
is Nicole right???
no shes not
what are the answers for MI
i'm with ya @bella
I can definitely help you with these two equations. Let's solve them step by step.
1. -2v - 7 = -23
To solve this equation, we need to isolate the variable "v" on one side of the equation.
First, let's simplify the equation by adding 7 to both sides:
-2v - 7 + 7 = -23 + 7
-2v = -16
Now, let's isolate the variable "v" by dividing both sides of the equation by -2:
-2v / -2 = -16 / -2
v = 8
Therefore, the solution to the equation -2v - 7 = -23 is v = 8.
2. x/4 - 5 = -8
Similar to the previous equation, we'll isolate the variable "x" in this equation.
First, let's simplify the equation by adding 5 to both sides:
x/4 - 5 + 5 = -8 + 5
x/4 = -3
Now, let's isolate the variable "x" by multiplying both sides of the equation by 4:
4 * (x/4) = -3 * 4
x = -12
Therefore, the solution to the equation x/4 - 5 = -8 is x = -12.
Remember to always double-check your answers by substituting the found values back into the original equations to make sure they satisfy the equations.
