A
26.35

B
25.54

C
23.34

D

x = 42.22 - 15.87

x = 26.35
Question 2
1 / -0

What is the value of (12.123 + 12.2 + 12.34) rounded to the nearest tenth?

A
36.3

B
36.5

C
36.7

D
36.9

Solution

12.123 + 12.2 + 12.34 = 36.663

To round the number to the nearest tenth, we look at the digit at the hundredths place.

Now, since the digit at the hundredths place is 6, the tenths place digit would be rounded up to 7.

So, the answer is 36.7.
