Question

Evaluate each expression if a = 4.1, b = 5.7, and c=0.3.

4. a+b-c
5. 10-(a+b)
6. B- c+2

Answer 1

• a+b-c = 9.5

• 10-(a+b) = 0.2

• b-c+2 = 7.4

Explanation:

4)

Given the expression

a+b-c

• a=4.1

• b=5.7

• c=0.3

substituting the values in the expression

a+b-c = 4.1+5.7-0.3

= 9.8 - 0.3

= 9.5

5)

Given the expression

10-(a+b)

• a=4.1

• b=5.7

• c=0.3

substituting the values in the expression

10-(a+b) = 10 - (4.1+5.7)

= 10 - 9.8

= 0.2

6)

Given the expression

b-c+2

• a=4.1

• b=5.7

• c=0.3

substituting the values in the expression

b-c+2 = 5.7 - 0.3 +2

= 5.4 + 2

= 7.4
