Question

What is the value of 3ab + c when a = 0.32, b = 0.45, and c = 7.2?

Answer 1

Answer:

7.632

Step-by-step explanation:

When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.

a = 0.32

b = 0.45

c = 7.2

3ab+c

3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32

0.96(0.45)+7.2 *Multiply the 0.96 to 0.45

0.432+7.2 *Add

7.632
