Answers

35 = 45 - n
think of it as money
45 dollars take away how many (n) = 35 dollars
45 - n =35
or you can subtract 45 from both sides
-n = 35-45

divide by -1 from both sides 
n = 10

Answer:

18° and 72°

Step-by-step explanation:

Complimentary angles form 90°

We have an angle (x) 4 times larger than the other (y).

Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.

Five years from now a father's age will be three times his son's age and 5 years ago he was seven times as old as his son was. what are their present ages?

Answers

Let's say the son is x years old now, 
In five years time, he will be (x+5) years old
The father's age in five years time is 3(x+5)
The son's age five years ago was x-5
The father's age five years ago was 7(x-5)
Five years ago and five years from now are 10 years apart. This means that the father's age five years from now is 10 years more than his age five years ago
7(x-5)+10=3(x+5)
7x-35+10=3x+15
7x-3x=15-10+35
4x=40
x=10
The boy is currently 10 years old
The father will be 3(x+5) in five years time=45
So the father is currently 40 years old 

You saved 850$ from your summer job last summer. You put it in a account that earns simple interest each month. After 9 Months your account is worth 1,003$. What percent interest did you earn each month?

Answers

Interest earned=$1003−$850=$153
Principal=$850
Time=9 months
Rate=Interest per month

Use the formula to solve for interest: (Interest)=(Principal)×(Rate)×(Time)
              153 = 850 
× R × 9
Simplify.
              153 = 7650 
× R
Divide both sides by 7650.
              0.02 = Rate
She earned 2% interest each month.
