-14 = 4a
Answer:
a = -3 1/2
Step-by-step explanation:
To solve the equation for a, divide each side by 4.
-14 = 4a
-14/4 = 4a/4
-14/4 = a
Simplify the fraction by dividing the top and bottom by 2.
-7/2 =a
This is an improper fraction, so change to a mixed number.
2 goes into 7 3 times with 1 left over.
-7/2 = -3 1/2
a = -3 1/2
-14=4a
=
a=

after the bus. The bus has a 15-minute head start and
is traveling at an average rate of 40 mph. Clever is
traveling at an average rate of 60 mph. How long does
Clever take to catch up to the bus? Draw a diagram to
solve the problem.
Answer:
Speed = Distance / Time
Distance = Speed x Time
Bus: 15 x 40 = 600 m
Clever: 600 / 60 = 10 minutes
Answer = 10 mins
Step-by-step explanation:

By solving a system of equations we will see that Sandy has 20 nickels and 15 dimes.
We need to define the variables:
We know that there are 35 coins so:
x + y = 35
And the total values if $2.50, then:
x*$0.10 + y*$0.05 = $2.50
Then our system is:
x + y = 35
x*$0.10 + y*$0.05 = $2.50
To solve this, we need to isolate one of the variables in one of the equations. I will isolate x on the first equation:
x = 35 - y
Now we replace this on the other equation:
(35 - y)*$0.10 + y*$0.05 = $2.50
$3.5 - y*$0.05 = $2.50
$3.50 - $2.50 = y*$0.05
$1.00/$0.05 = y = 20
So there are 20 nickels and the other 15 coins are dimes.
