So the first thing you can do is find out the amount charged without the initial fee.
41 - 8 = 33
Since they are charging $3 for each half of a mile, to find out how many half miles they drove, you have to divide 33 by 3, which means they drove 11 half miles.
Now, convert that into actual miles.
11 × 0.5 = 5.5
They drove 5.5 miles.
15/20...divide numerator and denominator by 5 = 3/4
Answer:
Step-by-step explanation:
1. 2x - 1 < x + 3
Subtract x and add 1 to both sides
2x - 1 - x + 1 < x + 3 - x + 1
x < 4
2. 5x - 1 > 6 - 2x
Add 1 and 2x to both sides
5x - 1 + 1 + 2x > 6 - 2x + 1 + 2x
7x > 7
Divide both sides by 7
7x/7 > 7/7
x > 1
3. x - 5 < 0
Add 5 to both sides
x-5 + 5 < 0 + 5
x < 5
<span> Pythagorean right triangle
a^2 + b^2 = c^2
Let the length of the ladder be x.
One side is x - 16.
The other side is x - 8.
</span><span>(x-16)^2 + (x-8)^2 = x^2
</span>
x^2 - 32x + 256 + <span>x^2- 16 x+64 = x^2
x^2 - 48 x + 320 = 0
( x- 40 ) (x-8) = 0
x = 40 or x= 8
we discard the second so x = 40
