The answer is C.
3 (20-14)=44
(distribute the 3, then subtract)
Step-by-step explanation:
<u>Step 1: Complete the first equation</u>
0.1 is a tenth, therefore if we have 15.3 then we have 153 tenths.
Step 2: Complete the second equation
15.3 / 3 = 5.1
0.1 is a tenth, therefore if we have 5.1 then we have 51 tenths.
<u>Step 3: Complete the third equation</u>
15.3 / 3 = 5.1

11x+9x = 6/3
20x = 2
x = 2/20
x = 0.1</span>
