Answer:
11.37 lb-ft
Step-by-step explanation:
We are given that
Force,F=3 pounds

Let Point A (3,7) and point B(8,8)
We have to find the work done by the force.

feet
We know that Work done by the force

Substitute the values

Hence, the work done by the force =11.37 lb-ft
Answer: (6,16)
(6,2)
(-2,8)
(14,8)
The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.

We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with
,
,
, and
respectively since each one is 1 point more than the last.
Add all of these values up and set it all equal to
.

Now, simplify.

Subtract
on both sides.

Divide both sides by
.

Since Louise's score is
, the answer is
.
<h3>Double-checking</h3>
To verify our answer, add the point totals
,
,
, and
.
This equals
, so we can be sure the answer is correct.
A system of equations for this would be
19x + 11y = 273
and
12x + 17y = 283.
X is the amount of minutes to solve one long division problem and y is the amount of minutes to solve a graphing problem.
How To Solve This System of Equations.
Multiply both by 17 and 11 respectively for them to have the greatest common factor for y. So now both equations are:
323x + 187y= 4641
132x + 187y= 3113.
Subtract both equations and you have left:
191x = 1528.
Divide both sides by 191 and you find x.
X = 8.
Answer
It takes Sally 8 minutes to do one Long Division Problem.
