Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.

Step-by-step explanation:
Let's figure out where the ant is after each step.
Step 1
Start at +3.0
Move left <u> - 1.5
</u>
Now at +1.5
Step 2
Start at +1.5
Move right <u> + 4.9
</u>
Now at +6.4
Step 3
Start at +6.4
Move left <u> - 7.6
</u>
Now at -1.2
The ant is now at -1.2 cm.
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
