The equation below shows the relationship between the temperature in degrees celsius, c, and degrees fahrenheit, f:
c = 5 over 9(f − 32)
which of the following formulas correctly solves for f?
f = 9 over 5c + 32
f = 9 over 5c − 32
f = 9c + 32 over 5
f = 9c − 32 over 5

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

Now, we solve for F,

Multiply both side by 9,

Open the brackets,

Divide both side by 5,

Solve,

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

Therefore, Option 1 is correct.

they are simplified

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
