(7x + 2)(x - 2) are the factors
Answer:
a) 245$
b) 8 hours
Step-by-step explanation:
a) 7 hours x 35$ = 245$
b) 252$ - 40$ (because the fixed charge isn't related to the hours.
=212$ for how many hours?
divide 212 by 26.50$
212/26.5= 8 hours
I believe there are 20 quarters and 3 nickels.....
Total value of the jar is $5.15.....
Quarters are worth 25 cents
And nickels are worth 5 cents.
First you know that there are 4 quarters in a dollar.
You have 5 dollars so you do 4 x 5 = 20
So five dollars ($5.00) is 20 quarters.
And you still have 15 cents left.
Because quarters are 25 cents the rest are nickels.
Nickels are worth 5 cents so you'd do 5 x 3 = 15.
15 cents!
Add all this together and get $5.15.
So your answer is
There are 20 quarters and 3 nickels in the jar.
So what you want to do for all of these is move the variable that you want to be the subject to one side of the equation and the other ones to the other side, then divide.
For example:
With number 1, m = 3n + 2p, since you want to make p the subject, first single out p by subtracting 3n from both sides.
m - 3n= 3n + 2p - 3n
2p = m - 3n
Then divide everything by 2.
2p / 2 = m/2 - 3n/2
p = , you could also say 1/2m - 3/2n
p = 1/2m - 3/2n
Next question: just do the same thing.
a = 3c - 4
a + 4 = 3c - 4 + 4
3c = a + 4
/3 /3 /3
c = 1/3a + 4/3
Next question: same process.
P - 2a = 2a - 2a + 2b
2b = P - 2a
/2 /2 /2
b = 1/2P - a
