Answer:
Step-by-step explanation:
This is an inequality problem. If we want Joe's service to be cheaper, then the inequality is set up like this:
14x + 250 < 22x
where x is the number of hours.
Solving we get
250 < 8x so
31.25 < x or equivalently,
x > 31.25
That means that all hours less than 31.25 would put Bill's as the cheaper service. All hours greater than 31.25 would put Joe's as the cheaper service.
1. yes because they go into it equally
2. 2 3 4 5 9 10
3. 3 5 9
4. 300 and 400 because 100 x 3 is 300 and 4 x 100 is 400
5. 9000 and 5000 because 9 x 1000 is 9000 and 5 x 1000 is 5000
That's going to depend a lot on what you want to "do" to it.
I'm going to assume that you want to find a number for 'x' that makes
the whole equation a true statement. Here's how I would do it:
<u> 5 ln(x) = 35</u>
Divide each side by 5: ln(x) = 35/5
ln(x) = 7
Raise 'e' to the power of each side: e^[ ln(x) ] = e⁷
But e^[ ln(x) ] is just 'x'. So x = e⁷ = <em>1,096.633...</em> (rounded)
That's the only number you can write in place of 'x'
and make the original equation true.
11 5/8 in = 11.625 in
9 3/4in = 9.75 in
10 1/2 in= 10.5 in
11.625+9.75+10.5= 31.875in
To find the average divide the total of inches by the amount of pieces there are to find the average:
31.875 / 3 = 10.625in
