Answer:

Option 1 - F = 9 over 5C + 32

Step-by-step explanation:

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

C = 5 over 9(F − 32)

To find : Which of the following formulas correctly solves for F?

Solution :

We can write the equation as

 C=\frac{5}{9}(F-32)

Now, we solve for F,

Multiply both side by 9,

 9C=5(F-32)

Open the brackets,

 9C=5F-160

 9C+160=5F

Divide both side by 5,

 \frac{9C+160}{5}=F

Solve,

 \frac{9}{5}C+32=F

So, The value of F is F=9 over 5C +32.

Therefore, Option 1 is correct.

<h3>Answer:</h3>

System

  • p + m = 10
  • 0.8m = 0.4·10

Solution

  • p = m = 5 — 5 lb peanuts and 5 lb mixture
<h3>Step-by-step explanation:</h3>

(a) Generally, the equations of interest are one that models the total amount of mixture, and one that models the amount of one of the constituents (or the ratio of constituents). Here, there are two constituents and we are given the desired ratio, so three different equations are possible describing the constituents of the mix.

For the total amount of mix:

... p + m = 10

For the quantity of peanuts in the mix:

... p + 0.2m = 0.6·10

For the quantity of almonds in the mix:

... 0.8m = 0.4·10

For the ratio of peanuts to almonds:

... (p +0.2m)/(0.8m) = 0.60/0.40

Any two (2) of these four (4) equations will serve as a system of equations that can be used to solve for the desired quantities. I like the third one because it is a "one-step" equation.

So, your system of equations could be ...

  • p + m = 10
  • 0.8m = 0.4·10

___

(b) Dividing the second equation by 0.8 gives

... m = 5

Using the first equation to find p, we have ...

... p + 5 = 10

... p = 5

5 lb of peanuts and 5 lb of mixture are required.

12.) You purchased a scooter for $6,800 when it was on sale for 30% off. What was the original price of thescooter?
Rina8888 [55]

SOLUTION:

Case: Percentages

Method:

The sale price after 30% off is $6800

Let the original price be 'x'

30% off means 70% of the original price

\begin{gathered} \frac{70}{100}\times x=6800 \\ 0.7x=6800 \\ x=\frac{6800}{0.7} \\ x=9714.2857 \end{gathered}

Final answer: (Nearest cents)

The original price was $9714.29
