In this problem, you are tasked to find the value of x.
-12 = 3x + 3
This is the same as:
3x + 3 = -12
You have to transpose the 3 to the other side to solve the
equation.
3x = -12 – 3
3x = -15
x = -5
Answer:
Option C
Step-by-step explanation:
12 miles / 3 mph would equal 4 hrs of travel. He left at 11 AM because 2:00 - 4 hrs is 11 AM.
Answer:
RT = 20
Step-by-step explanation:
Given that,
Point S lies on the line segment RT.
We have, ST = 3x-8, RT = 4x and RS = 4x-7
It is clear that, RT = RS+ST
Putting the values, we get :
4x = 4x-7 + 3x-8
Taking like terms together,
4x-4x-3x = -7-8
-3x = -15
x = 5
Put the value of x in RT = 4x.
So,
RT = 4(5)
RT = 20
Hence, length of RT = 20.
The answer is x=2
8-3x=2
You minus 8 from each side=-3=-6
You then divide -6 by -3=2
A negative number divided by a negative number stays negative.
The correct answer is 4> -3
