All you do is multiply 22 times 8 which is 176 then you multiply 8*4
Answer:
The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).
5(n-4)=(4n-12)
First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.
Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.
(5n-20)=(4n-12)
n-20=-12
Next: Add 20 to both sides to eliminate the constant from the left side of the equation.
n-20=-12
n=8
The unknown number is 8.
The interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds
<h3>How to interpret the expression?</h3>
The expression is given as:
-10c/60 seconds
From the question, we understand that:
The temperature decreases by 10c every minute
When converted to seconds, we have:
10c/60
Hence, the interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds

first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
