Hey there!
speed=distance/time.
s-speed
s=12/3
s=4
The speed of the car is 4 mph
Hope this helps:) Let me know if you have any questions.
The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>

We have 7/x = 24/60, where x is number of miles;
Then, x = ( 7 x 60 ) / 24 = 17.5 miles;
<u><em>Answer: m=2 and 2=m *The answer should be have positive sign.*</em></u>
Step-by-step explanation:
4m-7+10=15-2m ← Group like terms
add/subtract numbers
-7+10=3
4m+3=15-2m
subtract by 3 both sides of an equation.
4m+3-3=15-2m-3
simplify.
4m=-2m+12
add 2m both sides of an equation.
4m+2m=-2m+12+2m
simplify.
6m=12
divide by 6 both sides of an equation.
6m/6=12/6
simplify by equation.
12/6=2
6*2=12
2*6=12
12/2=6
m=2
Hope this helps!
Thanks!
Have a great day!
