In order to solve this equation you must first simplify, then you re-range the terms, then solve.

12(x + -360) = 120

12(-360 + x) = 120

(-360 \times 12 + x \times 12) = 120

(-4320 + 12x) = 120

+ 4320+ 4320

12x = 4440

4440 \div 12 = 370

x = 370

Which means your answer is "x=370."

Hope this helps.

Answer:

A

Step-by-step explanation:

Given

a = \frac{1}{x} - \frac{1}{y} = \frac{y-x}{xy} ← as a single fraction

Thus

\frac{1}{a} = \frac{1}{\frac{y-x}{xy} } = \frac{xy}{y-x} → A

I need to finish these so I don't fail, help me out
Dima020 [189]

Answer:

y < -2x - 4

Step-by-step explanation:

This is a guessing game. You just have to plug and chugg to find your answer.

Look at the table they gave you and plug in the x and y value into the given equations and see if they're true or not.

For example, I used the point x=-2 and y=1 from the table.

I plug that into y < -2x - 4 and got a false statement:

y < -2x - 4

(1) < -2(-2) - 4

1 < 4 - 4

1 < 0

this is false because one cannot be less than zero. Therefore this equation is the wrong one.

If you tried to plug in x=-2 and y=1 into the other 3 equations you'll see that they'll be correct.

70=(4x+36)/2 figure this out please
adell [148]

Answer:

\boxed{\bold{\huge{\boxed{x = 26}}}}

Step-by-step explanation:

70 = \frac{4x+36}{2}

<u>Multiplying both sides by 2</u>

70 * 2 = 4x+36

140 = 4x+36

<u>Subtracting 36 to both sides</u>

140 - 36 = 4x

104 = 4x

<u>Dividing both sides by 4</u>

26 = x

OR

x = 26

1.84repeating as a mixed number in simplest form
Dennis_Churaev [7]

Hello!

I'm assuming you're looking for 1.848484.

The first thing we want to do is get rid of the repeating part. The way we can do this is subtract the number we are given from itself multiplied by a power of 10. So, set 1.8484... = x. And based off of that, find 100x. This is because the next time the decimal repeating will become .8484 again is after two numbers pass.

1.848484... = x

184.8484... = 100x

Next, subtract x from 100x. This will get rid of the repeating decimal.

100x - x = 184.8484... - 1.8484

99x = 183

Finally, divide both sides by 99. This leaves us with a fraction.

99x = 183

x = 183 / 99

Simplify this fraction.

183 / 99 -> 61 / 33

Finally, turn it into a mixed number, as this is the form your question is looking for.

61/33 -> 1 28/33

Hope this helps!
