Answer:
12 hours
Step-by-step explanation:
Let's set the speed as "s".
Remember that distance = speed * time
So, plugging the numbers given...
7 = s * 8.4
Divide both sides by 8.4
s = 5/6
Now, plug this into the distance = speed * time, with the distance being 10. Set the time as "t"
10 = 5/6 * t
Divide both sides by 5/6
12 = t
So, it would take 12 hours for the snail to crawl 10 miles.
Answer:
h = 19cm
Step-by-step explanation:
The area of a parallelogram =
A = bh
285cm² = 19×h
285 = 19h
divide by 19
285/19 = 19h/19
h = 15cm
Answer:
Step-by-step explanation:
The following ratio solves the problem
AM/MN = x / MP
(67.2 - 32) /67.2 = x / 81.9
35.2 / 67.2 = x / 81.9
Cross Multiply
67.2 * x = 81.9 * 35.2
67.2 x = 2882.88
Divide by 67.2
x = 2882.88 / 67.2
x = 42.9

Answer:
\frac{\left(5x+1\right)\left(3x+1\right)}{2x-y}
Step-by-step explanation:
15x^2+8x+1:\quad \left(5x+1\right)\left(3x+1\right)
add on 2x -y as the denominator of the fraction
