Answer:

-12x - 42.

Step-by-step explanation:

-6 * 2x - 6 * 7

Now, multiply -6 by 2x and -6 by 7:

-12x - 42

So, the simplified expression is -12x - 42.

Answer: -12x - 42

Step-by-step explanation:

First, -6(2x) is -12x then -6(7) is -42

That makes -12x - 42

Given ~ and AB = 20, CA = 8, and US = 9, what is ST?
Does anyone know?

Answers

ST would be 22.5. 
Assuming ΔABC and ΔSTU are similar, they have to be proportional, so you could create a proportion to figure it out: 8/20=9/? (if you need to know how I got that, message me). Then you could cross multiply. 9x20 is 45, so that means that the measure of ST times 8 has to equal 45. If you divide 45 by 8, you get 22.5, so that makes the measure of ST 22.5.

A scientist estimated that a mixture would need 3 milliliters of a chemical to balance. The actual amount needed was 7 milliliters. What was the percent error of the scientist's estimation?A. 133.33%
B. 3%
C. 42.86%
D. 57.14%

Answers

Answer:

57.14%

Step-by-step explanation:

Error(E)is defined as the percentage difference an estimate(e) amount is from the actual(a) amount. The actual amount need was 7 mililters and the estimate was 3 mililiters.

Error is defined as:

E=(a-e/a)*100

E=(7-3/7)*100=57.14

The percet error if the scientists estimation is 57.14%

Letter C is the answer

The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17:

Step 1: 5x − 2x − 3 = −2 + 17
Step 2: 5x − 2x − 3 = 15
Step 3: 3x − 3 = 15

Which of these is most likely the next step?

Answers

The next step is most likely to add 3 to both sides, so that 3 cancels out, and 15 turns into 18.

The answer is: Step 4: 3x = 18
(I don't know if you want me to continue or not, but I will) ;)

Then divide by 3 on both sides so that 3 cancels out and 18 turns into 6, and you have the value of x. 

Step 5: x = 6

You can check your answer by replacing x with 6.

5 · 6 - 2 · 6 - 3 = -2 + 17
15 = 15

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

3x = 18

How do I solve this?

Answers

1) Multiply out the 2 to the 10, so it will become 3x-5=20    2) Then solve:3x=25 3)x=25/3

3x-5/2=10

The first step, multiply both sides by 2.  
3x - 5 = 20 

Add 5 to both sides. 

3x = 25 

Then divide both sides by 3. 
x = 25/3 or 8.33333333...

1/5 of a number is 8. What is the number?

Answers

40 because 8 times 5 is 40 which makes 8 one fifth of 40 .
We set up a proportion: 8/?= 1/5

Cross multiply: 1*?= 8*5
⇒ ?= 8*5/1= 40

1/5 of 40 is 8.
