A small theater had 6 rows of 23 chairs each. Workers just removed 9 of these chairs. How many chairs are left?

129

Step-by-step explanation:

6 rows of chairs * 23 chairs in each row = 138 total chairs.

If 9 of these chairs were removed, that becomes 138 - 9 = 129.

There are 129 chairs left.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
