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

option (D) is correct.

formula that solves for C is  

Step-by-step explanation:

Given :  the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F as ,  

We have to find the correct formula that solve for C,

Consider the given formula,

We have to find formula for C,

Thus, first subtract 32 both side, we get,

Now, multiply  5 both side, we get,

Now , divide both side by 9, we get,

Thus, formula that solves for C is  

Thus, option (D) is correct.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
