Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Step-by-step explanation:
The equation 
can be solved by squaring both sides:
We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:
The square root of 49 equals 7, but the square root of -1 is an imaginary number.
The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Answer:
I got 6.
Step-by-step explanation:
I picked my number to be 3. I took away 1 to make it 2. I then multiplied 2 by 3, to get 6.
It will take them 5 Hours to charge the same. The rental charge will be 510.
I did a manual computation per company: My computation is entirely based on trial and error.
Red Bus Co. has a fixed rental rate of 150 and additional rental of 72 per hour while Blue Bus Co. has a fixed rental rate of 240 and additional rental of 54 per hour. Both fixed rental rate are one time charges only and total rental will vary on the number of hours spent in using both vehicles.
Let's start with the Red Bus Co. I will be posting the charges per hour and its running balance. The running balance is the sum.
Fixed Rate 150 Running Balance: 150 => 150 + 0
Hr 1 72 222 => 150 + 72
Hr 2 72 294 => 222 + 72
Hr 3 72 366 => 294 + 72
Hr 4 72 438 => 366 + 72
Hr 5 72 510 => 438 + 72
I'll do the same process with Blue Bus Co.
Fixed Rate 240 Running Balanc: 240 => 240 + 0
Hr 1 54 294 => 240 + 54
Hr 2 54 348 => 294 + 54
Hr 3 54 402 => 348 + 54
Hr 4 54 456 => 402 + 54
Hr 5 54 510 => 456 + 54
2.25/100 x =630
x= 630 x 100/2.25
x= 28000
Answer:0.125
Step-by-step explanation:
There is only 1/8 that is whistle so convert into percent and get 0.125. Hope this helps
