Answer:
the answer should be 7a^3-4a^2-2a-87
Answer:
a = 3
Step-by-step explanation:
When you add the given value for a with 7, the resulting answer must be less than 11.
In this case, if: a = 3
Plug in 3 for a in the equation:
7 + a < 11
7 + 3 < 11
10 < 11 (True).
A) a = 3 is your answer.

The DJs unit rate is 5 songs for every 1 commercial.
I found this by dividing both the commercials and the songs by their greatest common factor, or 2.
18 ÷ 3 is 6, which means that Daniel is 6, and there is a 12 year gap between Steve and Daniel.
12 x 2 is 24, so therefore when Steve is 24, Daniel will be 12, so Steve is twice as old as Daniel:)
Answer: "Subtract 6 from both sides, and then divide by 2. The solution is x = 8"
Step-by-step explanation: Lets solve for 2x + 6 = 22
Step 1 Subtract 6 from both sides: 2x + 6 - 6 = 22 - 6 2x = 16
Step 2 Divide by 2 in both sides: 2x/2 = 16/2
Step 3 The answer: x = 8
