It is given in the question that
A city had population 67,255 on January 1,2000, and its population has been increasing by 2935 people each year since then.
Here initial population , b, is 67255, and the rate of increase of population is 2935 people each year. And that's the value of the slope .
Using slope intercept form, which is
And substituting the values of m and b, we will get

Answer:
Number of messages Salma sent = 7
Number of messages Brian sent = 16
Number of messages Chang sent = 32
Step-by-step explanation:
Let
Number of messages Salma sent = n
Number of messages Brian sent = n + 9
Number of messages Chang sent = 2(n + 9)
Total messages sent = 55
n + (n + 9) + 2(n + 9) = 55
n + n + 9 + 2n + 18 = 55
4n + 27 = 55
4n = 55 - 27
4n = 28
n = 28/4
n = 7
Number of messages Salma sent = n = 7 messages
Number of messages Brian sent = n + 9 = n + 9 = 16 messages
Number of messages Chang sent = 2(n + 9)
= 2(7 + 9)
= 2(16)
= 32 messages
Answer:
65/9
Step-by-step explanation:
3 1/3=(3*3+1)/3=10/3
2 1/6=(2*6+1)/6=13/6
10/3*13/6=130/18=65/9
Answer:
Karl prepared 30 liters in 5 hours
Step-by-step explanation:
The total amount of juice Karl prepares per unit time can be expressed;
T=U×h
where;
T=total number of liters of juice prepared
U=number of liters prepared per unit time
h=number of working hours
In our case;
T=12 liters
U=U
h=2 hours
replacing;
12=U×2
2 U=12
U=12/2
U=6 liters per hour
The unit rate=6 liters per hour
Solving for 5 hours
Total quantity of juice prepared=Unit rate×number of hours worked
where;
Unit rate=6 liters per hour
Number of hours worked=5 hours
replacing;
Total quantity of juice prepared=(6×5)=30 liters
Karl prepared 30 liters in 5 hours
