Answer:
Step-by-step Simplifying
6 + -3x = 4 + -1x + -3 + -2x
Reorder the terms:
6 + -3x = 4 + -3 + -1x + -2x
Combine like terms: 4 + -3 = 1
6 + -3x = 1 + -1x + -2x
Combine like terms: -1x + -2x = -3x
6 + -3x = 1 + -3x
Add '3x' to each side of the equation.
6 + -3x + 3x = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 + 0 = 1 + -3x + 3x
6 = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 = 1 + 0
6 = 1
Solving
6 = 1
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Answer: A = 7 unit^2
Explanation:
First let’s cut the shape into 1 square and 1 trapezoid.
After that we can calculate the 2 polygons individually
Find area of square:
A = 2 x 2 = 4
Find area of trapezoid:
A = (2 + 1)2/2 = 3
Find area of the whole shape
Answer:
True depending on what you are comparing it to.
Step-by-step explanation:
A pulley would help lighten the load that you are trying to pull up, which may make it easier for you to get the load to your designated area. The more complicated it is, usually the more 'lighter' it becomes, or the less force you have to exert.
For example, you will have to give a 100% energy in trying to life a heavy box. However, if you use a simple pulley (only one), you may only have to exert 75% more energy, for the weight is significantly lower.

Answer: 8
Step-by-step explanation:
Given
Lian has 
and she has twice as many dimes as nickels
Suppose she has 
nickels
So, the number of dimes is 
Nickel is equivalent to 5 cents and dime is equivalent to 10 cent
Therefore she has 8 dimes with her.
