Answer:1.5 hours
Step-by-step explanation:
$8.50 is for 1/2 hour
In $25.50, the can use for (25.5*.5)/8.5 = 1.5 hours

<u>Answer:</u>
The geometric mean between each pair of numbers 
<u>Solution:</u>
The Geometric mean between two numbers a and b is given as Geometric mean =
--- eqn 1
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.
From question, given that two numbers are 
Hence we can say “a” =
=7
Similarly “b” =
= 29
We have to find the geometric mean between “7” and “29”
By using equation 1,
Geometric mean between 7 and 29 =
= 14.24
Hence the geometric mean between 
Answer:
y=2 and x=1
Step-by-step explanation:
2y=7y-14+4
2y-7y=-14+4
-5y=-10/-5
y=2
4x=6-4+2x
4x-2x=6-4
2x=2/2
x=1
