Answer:
18.9c - 11.2d + 9.3f
Step-by-step explanation:
<u>First, write the equation as adding all the parentheses together like so:</u>
(9.7c - 1.9d) + (9.2c + 1.1f) + (8.2f - 9.3d)
<u>Remove the parentheses:</u>
9.7c - 1.9d + 9.2c + 1.1f + 8.2f - 9.3d
<u>Collect like terms (9.7c and + 9.2c):</u>
18.9c - 1.9d + 1.1f + 8.2f - 9.3d
<u>Collect like terms again (1.9d and - 9.3d):</u>
18.9c - 11.2d + 1.1f + 8.2f
<u>Collect like terms again (1.1f + 8.2f)</u>
18.9c - 11.2d + 9.3f

Answer: 12
Step-by-step explanation:
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24
