Answer:
x−3=x−3
Step-by-step explanation:
Evaluate (2x−1)−7, then set it equal to 2.
Subtract 7 from −1 = 2x−8
Solve 2x−8=2.
Move all terms not containing x to the right side of the equation.
Add 8 to both sides of the equation=2x=2+8
Add 2 and 8=2x=10
Divide each term by 2 and simplify.
Divide each term in 2x=10 by 2=2x/2=10/2
Cancel the common factor of 2
Cancel the common factor=10/2
Divide x by 1=x=10/2
Divide 10 by 2=x=5
Remove parentheses=x−3
List all of the solutions.

(2x−1)−7=2=x=5
x−3=x−3
Answer:
Step-by-step explanation:
A fixed pulley consists of a wheel fixed to a shaft and is used in conjunction with a belt to transfer energy to another fixed pulley. A movable pulley consists of a shell, a movable wheel and a rope. Movable pulleys are also know as block and tackle.
<span>A-2b=2
A-b=6
</span>
<span>A-2b=2
-2(A-b=6)
-2A+2b= -12
A-2b=2
-2A+2b = -12
-------------------
-A = -10
-A/-1 = -10/-1
A = 10
a-b=6
10 - b = 6
10-10-b = 6 -10
-b = -4
-b/-1 = 14/-1
b= 4
Check
a - 2b =2
10 - 2(4) =2
10 - 8 = 2
2=2

Answer:
A. -0.93
Step-by-step explanation:
It is a negative due to the scatter plot line decreasing as the precipitation increases, which cancels out C & D. Then, it is decreasing rapidly, which portrays it as closer to -1 than 0, meaning the answer is A.
