If 4x + 3x - 2(x + 5) = -9, then x = ?
A-12
B
C
Is
D
213
E
"15

the answer is 5

Step-by-step explanation:

1. first you need to take -2 and use the distributive property on (x + 5). when you do that you should get -2x -10.

2. 2nd then your equation should look like 4x + 3x -2x -10 = -9.  so after you get this equation you then add 4x + 3x. you should get 7x and your equation should look like 7x -2x -10 = -9.

3. 3rd the next step is to take 7x and subtract it from -2x. when you get dont doing this you should get 5x and then your equation will look like 5x -10 = -9.

4. 4th now we need to get all the normal numbers to one side. so you will add a positive 10 to the negative 10. when you do that the numbers cancel out. you have to do this to both sides. so you will add a positive 10 to the negative 9 and you should get positive 1. when you complete this step your equation should look like 5x = 1.

5. 5th you take 5x and divide it by 1 and you should get 5. 5 is your answer.

hope this helped!

p.s it would be cool if you gave me brainliest.

Correct answer choice is:

C. A stopwatch

Explanation:

The best a decent eye will do is fix a reading to one tenth of a second, that is so the design of the stopwatch. The digital stopwatch has 2 digits on the far side the seconds, thus it further separates the time in hundredths of a second. Since it's simple to scan to hundredth of a second, that's its design.
