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
Hope this helped!
