Step-by-step explanation:
We need to first find out how much 400% of 170 is and then add that increase to the original 170 people.
4(170) = 680 and
680 + 170 = 850 people after 3 years.
Answer:
The equation that models the relationships between 
, the number of hours Mark reads, and , 
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every 
hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where 
represents rate of change and 
represents the y-intercept or the initial value.
Rate of change =
The initial value 
as Mark starts reading from 0.
So, the equation is:
8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
