Question

Someone who is good with Algebra I Equations and Inequalities?

Answer 1

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F.

\[c=\frac{ 5 }{ 9 }(f-32)\]Which of the following formulas correctly solves for F?

Answer 2

what are the formulas

Answer 3

\[f=\frac{ 9 }{ 5 }c+32\]
\[f=\frac{ 9 }{ 5 }c-32\]
\[f=pc+\frac{ 32 }{ 5 }\]
\[f=9c-\frac{ 32 }{ 5 }\]

thx

Answer 11

I actually have one right now.


Below are the steps to solve an equation:

Step 1: |x - 2| + 3 = 7
Step 2: |x - 2| = 7 - 3
Step 3: |x - 2| = 4

Which of the following is a correct next step to solve the equation?

x + 2 = -4

-x - 2 = 4

x + 2 = 4

x - 2 = -4

Answer 12

ok I think the answer is the last one but I am not positive so I am going to mention @zepdrix because he is great at this kind of stuff

Answer 13

Oh, okay. Thanks.

Answer 14

@zepdrix when giving me the answer, could you also show the steps - if you want. - you dont have to - i know its too long.

Answer 15

The 4th answer is part of the next step to solve the absolute value equation.

Answer 16

thanks @mathstudent55

Answer 18

This is how you'd solve the equation:

Step 1: |x - 2| + 3 = 7
Step 2: |x - 2| = 7 - 3
Step 3: |x - 2| = 4

Step 4: x - 2 = 4 or x - 2 = -4
Step 5: x = 6 or x = -2

Notice that Step 4 does include the 4th choice, x - 2 = -4, but to solve the equation correctly, Step 4 needs to also include x - 2 = 4.

Answer 19

I just want to see if you can check if I got this right - Solve for pi: C = 2pir.
Now the way I would solve this I would come up with pi = c / 2 / r, but these are the answer choices:

pi equals 2 times C over r

pi equals C over quantity 2 times r

pi pi equals C over r

pi equals r times C over 2

I chose the second one (B).

Answer 20

Your answer is correct, but a complex fraction is not the simplest form you can have, so it can be simplified.

Answer 21

\(C = 2 \pi r\)

\(C = 2r \pi \)

\(C = (2r) \pi \)

Since you want \( \pi \) by itself, divide both sides by what is multiplying \( \pi \), 2r:

\(\dfrac{C}{2r} = \pi \)

\( \pi = \dfrac{C}{2r} \)

You are correct.

Answer 22

Thanks.

Answer 24

A company did a quality check on all the packs of nuts it manufactured. Each pack of nuts is targeted to weigh 18.25 oz. A pack must weigh within 0.36 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured nuts?

x < 17.89 or x > 18.61 because |x - 18.25| > 0.36

x < 17.89 or x > 18.61 because |x - 0.36| + 18.25 > 0

x < 18.25 or x > 18.61 because |x - 18.25| > 0.36

x < 18.25 or x > 18.61 because |x - 0.36| + 18.25 > 0
