Answer:
7x + 21
Step-by-step explanation:
7(x+3)
7x + 7(3)
7x + 21
-9x + 17 = 6x - 27 + x
Set equation equal to 0
Add 9x to the other side and subtract 17 to the other side
6x - 27 + x + 9x - 17 = 0
Combine like terms
6x + x + 9x = 16x
-27 - 17 = -44
16x - 44 = 0
Now you can solve for x like normal
16x = 44
x = 2.75
The word problem gives you the information you need to solve it.
5 batches of chili were made using 63.5 kg of beans total. You can assume the same amount of beans were used in each of the 5 batches, so ...
your equation would be:
63.5 ÷ 5 = # of beans in each batch.
63.5 ÷ 5 = 12.7
12.7 kg of beans were used in each of the 5 batches.
Check step:
12.7 × 5 = 63.5
6x^5 - 5x^4 + 6x^3 - x^2 + 12x - 31
The only like terms are the 0 exponent place.
