2+4a=-10
First, subtract 2 from both sides.
4a=-12
Then divide 4 from both sides.
a=-3

Answer:
92%
Step-by-step explanation:
because there are 100 squares and 92 are shaded
Explanation:
N= 3/4 or n= -5/3
8 am at 0
8:18 at 4.5
8:48 at 7.5 miles ???
18 min = .3 hour
48 min = .8 hour
in first .3 hours speed = 4.5/.3 = 15 mph
in next .5 hours = speed = 3/.5 = 6 mph
average speed for the whole trip = 7.5 miles/.8 hours = 9.375 mph
To run the these figures to 3 decimal places
you need to count from the digit after the decimal point until you reach the 3rd number which is 2
so now the answer is 2470.283
This is because the decimal point lies between 2 and 7 and since 7 is great than 5 we add 1 to the 2 making it 3
