The answer to your question is A
Let x be the number of sheets Raj had before printing.
sheets per copy= 25/2 = 13(round up)
x = 10+ 13(22)
x = 296.
Raj had 296 sheets of paper before printing.
X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78
Answer:
It will take 554 years
Step-by-step explanation:
Here, we want to estimate the time when t will be $50
We can rewrite the exponential equation as;
y = 200(1-0.0025)^t
In this case, y = $50 and we want to calculate t
so, we simply proceed to substitute the value 50 for y
we have this as ;
50 = 200(1-0.0025)^t
50/200 = (1-0.0025)^t
1/4 = 0.9975^t
0.25 = 0.9975^t
Take the natural logarithm of both sides
ln 0.25 = ln 0.9975^t
ln 0.25 = t ln 0.9975
t = ln 0.25 / ln 0.9975
t = 553.8 = 554 years
The bike will be $50 in 554 years
100%/x%=95/38
(100/x)*x=(95/38)*x - we multiply both sides of the equation by x
100=2.5*x - we divide both sides of the equation by (2.5) to get x
100/2.5=x
40=x
x=40
now we have:
