Question

Evaluate the temputure formula f=1.8C + 32 for C=40

Answer 1

Answer:
f=104

Explanation:
We are given the formula:
f=1.8C+32
This is a temperature formula. We want to find the degrees Fahrenheit for 40 degrees Celsius. Plug 40 in for C.
f=1.8C+32 (C=40)
f=1.8(40)+32
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply 1.8 and 40
f=72+32
Add 72 and 32.
f=104

When C=40, f=104. So, 40 degrees Celsius is equal to 104 degrees Fahrenheit.

Answer 2

Answer:

1.8 × 40 + 32 = 104
