How do you do simple interest in math
Kay [80]

simple interest:

principal x ( 1 + (rate as decimal x number of years))

 example if you put 100 dollars in a bank for 5 years at 5% interest at the end of the 5 years you would have:

100 x (1+(0.05 x 5)) = 100 x (1+(0.25)) = 100 x 1.25 = 125 dollars


125-100 = 25 dollars interest

1/x + 1/4 = 7/12 solve for x
Licemer1 [7]
Given equation is
\frac{1}{x} +  \frac{1}{4} =  \frac{7}{12}

We can solve it by subtracting 1/4 both side
\frac{1}{x} +  \frac{1}{4} -  \frac{1}{4} =  \frac{7}{12} -  \frac{1}{4}

\frac{1}{x} =  \frac{7}{12} -  \frac{1}{4}
                          =  \frac{7 - 3}{12}
                          =  \frac{4}{12}
                          =  \frac{1}{3}

So \frac{1}{x} =  \frac{1}{3}
On comparing x = 3.

SO the solution of equation is x = 3

<h2><u>Solu</u><u>tion</u><u>:</u></h2>

360° ÷ 10 ÷ 2 = 18°

So the length of the decagon side is:

10 × tan18° × 2 = 20 × tan18°

The area is: ½ × 20 × tan18° × 10 × 10 = 1000 × tan18°

≈ 324.9

Paul and Quinn share some money in a ratio 3:2, Paul gets 60 more than Quinn, how much does Quinn get
wlad13 [49]

Answer: 120

Step-by-step explanation:

3+2=5

Let x be the amount of money to be shared

Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x

Therefore

(3/5)x= (2/5)x + 60

(3/5)x - (2/5)x= 60

(x/5)=60

Cross multiply

x= 60*5=300

It means that Quinn’s share is (2/5)(300)= 120
