Answer:

First one is 13. The second is 12

Step-by-step explanation:

First Scenario:

The entire line is a total of 23. Above the line it creates three segments which break up the 23 in different parts. Therefore, in other words, (x - 6) + (9) + (2x - 19) = 23. So I added all my liked terms together and simplified to get me the value of 13.

Second Scenario:

Just like in the first scenario, the second scenario provides the information that the entire line is 32. However in this case the line is split up in two different sections as indicated above the line. In which provides you with the information with the two line segments being ? (or x in this case) and 20. Therefore you would set it up the same way as in the first scenario because these two parts added together gives us the entire length of the line. So I said x + 20 = 32, which in return gave me the value to be 12.

Degrees Celsius and degrees Fahrenheit are related by C=5/9(F-32).What is F in terms of C?
valina [46]

We are given: Degrees Celsius and degrees Fahrenheit are related by formula

C=\frac{5}{9} (F-32)

To find : Solve formula for F in terms of C.

Solution: We have , C=\frac{5}{9} (F-32)

First we need to get rid 9 from right denominator.

In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.

9*C=9*\frac{5}{9} (F-32)

9C = 5 (F-32).

Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.

9C = 5F - 160.

Adding 160 on both sides,

9C+160 = 5F - 160+160.

9C+160 =5F

Dividing both sides by 5, we get

(9C+160)/5 =5F/5.

\frac{9C+160}{5}=F

Splitting fraction 1/5, we get

F= \frac{1}{5} (9C+160).

Simplify the expression. 68 – 18 ÷ 3 • 6 Please help
MAXImum [283]
Remember PEMDAS (Parenthesis, Exponents, Multiplication, Divison, Addition and Subtraction)

Also note that Multiplication and Division needs to be done left to right and the same goes for Addition and Subtraction.

So in your problem, the first operation we need to do is division.

68 - (18/3) x 6
68 - 6 x 6

Now we do multiplication
68 - 6 x 6
68 - 36

Finally we do subtraction because that's the only operation we have left to do
68 - 36 = 32

So your answer should be 32.
