Please somebody help me with this... I’m so confused and it’s my last question

Answer for the first box = -31.67

Answer for the second box = 17.22

Work Shown:

Plug in F = -25 and solve for C

F = (9/5)C+32

-25 = (9/5)C + 32

(9/5)C + 32 = -25

(9/5)C = -25-32 ... subtract 32 from both sides

(9/5)C = -57

C = (5/9)*(-57) ... multiply both sides by 5/9, its the reciprocal of 9/5

C = -31.667 approximately

C = -31.67 rounding to 2 decimal places

This shows that -25 degrees F converts to roughly -31.67 degrees C.

Repeat the same basic steps, but now use F = 63

F = (9/5)C+32

63 = (9/5)C+32

(9/5)C+32 = 63

(9/5)C = 63-32

(9/5)C = 31

C = (5/9)(31)

C = 17.222 approximate

C = 17.22

If the temperature ranges from -25 degrees F to 63 degrees F, then this converts to the range of roughly -31.67 degrees C to 17.22 degrees C

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
