Step-by-step explanation:
You would do $67.86 divided by 7.8 lbs
Answer:
See below.
Step-by-step explanation:
So we started off with the equation:

And we subtracted x from both sides to acquire:

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:

Where m is the slope and b is the y-intercept.
If we rearrange our equation:

And put some parentheses:

We can see that this is indeed slope-intercept form.
And we can see that m is -1 and b is 2.
In other words, the slope is -1 and the y-intercept is 2.
Answer:
Where are the answer choice's??
Step-by-step explanation:
Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides
2x=78
Divide 2 from both sides
2x/2=78/2
X= 39
Step-by-step explanation:
Put the interior angle equal to 180.
It would look something like this:
x+45=180
-45 -45
180-45= 135 so the exterior angle would be 135!
