the answer is 75 minutes/1h 15m
15 pages × 350 words = 5250 words
5250 ÷ 70 = 75 minutes (1h 15m)
hope this helps!!
Answer:
Set this up as a proportion.
54/n = 75/100
Now solve for n and finish from here.

X-9^2
a number = x
decreased= subtracting
square of 9= 9^2
The $25.10 is 108% of the sale price.
$25.10 = 1.08n divide both sides by 1.08 = $23.24
To find the original price we must say that the sale price is 80% of the original price.
So we can write $23.24 = 80% of n or $23.24 = .8n Dividing both side by .8 we get $29.05.
So how can we do both of these in one equation? Here is one way.
($25.10/ 1.08) = .8n (I wrote it as two equation above since it explains it better)
There are other equations that will work too.
Answer:
Step-by-step explanation:
(x – 5)^2 + 3(x – 5) + 9 = 0
This is a quadratic equation in x - 5.
Let u = x - 5, then the quadratic equation becomes:
u^2 + 3u + 9 = 0
We can use the quadratic formula to solve for u.
Since u = x - 5, now we substitute x - 5 for u and solve for x.
