It is a an exponential function. And it is not A.
The answer is B)
Answer:
12d = 156
Step-by-step explanation:
Carlos is reading 12 pages / day
The total amount to read is 156
In order to find the days, you have to divide 156 by 12 or
Equation:
12d = 156; furthermore
d = 13 days, meaning it will take 13 days to read 156 pages.
Answer:
5
Step-by-step explanation:
Let's call the original number x.
So, the first student did x+23, and the other student did x-1.
You know that the first students result was 7 times larger than the other students. So, you can make the equation:
x+23=7(x-1)
x+23=7x-7
Then, do the algebra
-6x=-30
x=5
Answer:
A) 15x +79 = z
B) 15x +79 + 5x + 61 = 180
20x + 140 = 180
20x = 40
x = 2
Then using equation A)
A) 15 * 2 + 79 = z
30 + 79 =z
z = 109
