Answer:

f=\frac{9c}{5}+32

Step-by-step explanation:

c=\frac{5\left(f-32\right)}{9}

Switch sides:

\frac{5\left(f-32\right)}{9}=c

Multiply both sides by 9:

\frac{9\times5\left(f-32\right)}{9}=9c

5\left(f-32\right)=9c

Divide both sides by 5:

\frac{5\left(f-32\right)}{5}=\frac{9c}{5}

f-32=\frac{9c}{5}

Add 32 to both sides:

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

f=\frac{9c}{5}+32

rosijanka [135]

Answer:

11) 140/8 = 17.5

12) 38/3 = 12.667

13) 114/9 = 12.667

14) 7/2 = 3.5

15) 14/9 = 1.556

Step-by-step explanation:

To solve each problem you need to multiply the numerator by the whole number:

11) 7*20 = 140

12) 2*19 = 38

13) 6*19 = 114

14) 1*7 = 7

15) 7*2 = 14

Next, you put these numbers back into their corresponding numerators and divide:

11) 140/8 = 17.5     (You can simplify this fraction to 70/4 if needed)

12) 38/3 = 12.667  (This answer is rounded to the thousandths place)

13) 114/9 = 12.667  (This answer is rounded thousandsths place)

14) 7/2 = 3.5

15) 14/9 = 1.556       (This answer is rounded thousandths place)


**These are the improper fractions written as mixed ones** :

11) 17 1/2

12) 12 2/3

13) 12 2/3

14) 3 1/2

15) 1 5/9

I hope this helps!
