Answer:
x = -0.6 or 6/10
Step-by-step explanation:
(23x + 2) = (13x - 4)
23x + 2 - 2 = 23x
13x - 4 - 13x = -4
23x - 13x = 10x
-4 - 2 = -6
10x = -6
divide each by 10
10x / 10 = x
-6 / 10 = -0.6
x = -0.6 or 6/10
The difference of the two expressions. (23x+2)−(13x−4) is (10x -2).
What is an expression?Expression in mathematics is combination of variables with the use of operations and given rules. It can be in the form of equation, numbers etc.
Given expression,
(23x+2)−(13x−4)
And to find the difference,
we arrange the value of x with x and constant with constant in given expression,
(23x+2)−(13x−4) = 23x - 13x + 2 - 4
= 10x -2
Therefore, the difference of the two expressions. (23x+2)−(13x−4) is (10x -2).

Kim ran a mile in PE class. After resting for 1 hour her heart rate was 75 beats per minute. If her heart rate decreased by ⅖ , what was it immediately after she ran the mile?
Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.

Solve: | x-3 | + 2 = −3
|x−3|+2=−3|x-3|+2=-3
Move all terms not containing |x−3||x-3| to the right side of the equation.
|x−3|=−5
Remove the absolute value term. This creates a ±± on the right side of the equation because |x|=±x|x|=±x.
x−3=±(−5)
Set up the positive portion of the ± solution.
x−3=−5
Move all terms not containing x to the right side of the equation.
x= −2
Set up the negative portion of the ± solution.
x−3 =5
Move all terms not containing x to the right side of the equation.
x=8
The solution to the equation includes both the positive and negative portions of the solution.
x=−2, 8

A fishing adventure company rents fishing boats to tourists for day long fishing trips. Each boat can hold at most 60 people. Additionally, each boat can only carry no more than 8000 pounds of people and gear. Assume on average an adult weighs 150 pounds and a child weighs 75 pounds.

what happens to the potential energy of the atoms during a phase change ?
Answer:
The energy that is changing during a phase change is potential energy. During a phase change, the heat added (PE increases) or released (PE decreases) will allow the molecules to move apart or come together. Heat absorbed causes the molecules to move farther apart by overcoming the intermolecular forces of attraction.
Answer: I believe it turns into kinetic energy
Step-by-step explanation:
Kinect energy is the opposite of potential energy
