1. You can subtract everything with the same “value” so that means you can subtract 3x from 6x, 5y - 5y and 39 - 27. This will give you: 3x + 0 = 12. Because 0 isn’t anything you get 3x = 12. Dividing everything by 3 you get x = 4
My GUESS would be a year and 3/4 so almost two years in it would be 25% covered. Just a guess though.
Answer:
11 cm
Step-by-step explanation:
As Y is midpoint if XZ
XY=YZ=2a+1
WZ=WX+XY+YZ=28
a+1+2a+1+2a+1=28
5a+3= 28
5a=25
a=5
XY=2a+1
=2(5)+1
=10+1
=11 cm
This is the concept of commercial arithmetic, to solve for the time taken for loan of $548,048 to earn an interest of 50,000 given an interest rate of 9%. We use the formula:
A=P(1+r/100)^n
Where;
A=Future amount=548,048+50000=$598,048
P=principle
r=rate
n=time
thus;
598,048=548048(1+9/100)^n
1.0912=(1+0.09)^n
getting the logs of both sides
ln 1.0912=n ln1.09
thus
n=(ln 1.0912)/(ln 1.09)
n=1.01 years
The answer is 1 year
I'd suggest you begin by subtracting 4 / (x-4) from both sides. Doing that would leave you with 1 / (x-4) - 2 / (x+2) = 0.
LCD is (x-4)(x+2). Mult. all three terms by (x-4)(x+2). The resulting equation is
x+2 - 2(x-4) = 0. Then x+2 = 2x - 8 => x = 10
Subst. 10 for x in the original equation to verify that 10 is indeed a solution.
