Answer:
<u>-7b-7</u>
Step-by-step explanation:
First you have to distribute 11 throughout the parentheses.

Now we can combine like terms. (-18b, 11b, -33, 26)
and 


This is your simplified answer for your expression.
<u>-7b-7</u>
For the answer to the question above asking how many solutions does the system of equations have? y - 6x = -3 and 4y - 24x = -16. The answer is y - 6x = -3 -6x + y = -3 6x - y = 3
4y - 24x = -16 -24x + 4y = -16 24x - 4y = 16 reduces to 6x - y = 4
and this has no solutions
12.5%
First you need to find how much more the population increased (700 people)
Then you set up for a cross multiply and divide
700/5600 x/100
the 700 OVER 5600 people in fraction format shows the number of people arrived against the number of people already present
the x OVER 100 are the percentages, x representing what we need to find
The next step would then multiply 700x100 (cross multiply)
Then with the number you found 70,000 you would then divide by 5600 (divide)
This problem has no solution
