Answer:
for what?
Step-by-step explanation:
Answer:
7/12.
Step-by-step explanation:
=x/x+5.
x-5/x+5+4=⅛
x-5/x+9=⅛
x-5=⅛(x+9)
x-5=⅛x+1⅛
x-⅛x=1⅛+5
⅞x=49/8
7x=49
x=7
thus the initial fraction is x/x+5= <u>7</u><u>/</u><u>1</u><u>2</u>
A rational number is a fraction
Answer:
x = ±sqrt(5/2)
Step-by-step explanation:
6x^2−2=13
Add 2 to each side
6x^2−2+2=13+2
6x^2 = 15
Divide each side by 6
6/6x^2 = 15/6
x^2 = 5/2
Take the square root of each side
sqrt(x^2) = ±sqrt(5/2)
x = ±sqrt(5/2)
Answer:
The principal must be = $8991.88
Step-by-step explanation:
Formula for compound interest is:

Where A is the amount after 't' years.
P is the principal amount
n is the number of times interest is compounded each year.
r is the rate of interest.
Here, we are given that:
Amount, A = $15000
Rate of interest = 13 % compounded quarterly i.e. 4 times every year
Number of times, interest is compounded each year, n = 4
Time, t = 4 years.
To find, Principal P = ?
Putting all the given values in the formula to find P.

So, <em>the principal must be = $8991.88</em>
