Distance = rate*time
time = distance/rate
2.5 hours or 150 minutes
Answer:
It can be modeled with the equation 
but needs a starting population number to finish.
Step-by-step explanation:
To find the population in a future year, use the formula:
where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.
Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.

Answer: The solution of the system of equations is (1,7).</h3>
Step-by-step explanation: Given system of equations
y = 5x + 2 and
3x = –y + 10.
Substituting y= 5x+2 in second equation, we get
3x = -(5x+2) +10.
Distributing minus sign in (5x+2), we get
3x= -5x-2+10.
3x = -5x + 8.
Adding 5x on both sides, we get
3x+5x = -5x+5x +8
8x = 8.
Dividing both sides by 8, we get
8x/8 = 8/8
x = 1.
Plugging x=1 in first equation, we get
y = 5(1) +2
y = 5+2=7.
<h3>Therefore, the solution of the system of equations is (1,7).</h3>
Answer:
3.1
Step-by-step explanation:
3 1/2=3.5
2/5=0.4
3.5-0.4=3.1
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
