Ok so
cost=setupfee+costused
costused=(number of months) times (cost per month)
if we represent number of months as x
we know cost per month is 18
18x is costused
and in 2 m onts, he paid 81 so
81=startup fee +18x
2 monts so x=2
81=startupfeee+36
subtract 36
45=startup fee
5 monts is x=5
45+18(5)=45+90=135
A. cost=18x+45
B. $45
C. $135
Answer: Two column proof.
Explanation :
A two-column proof is one common way to organize a proof in geometry.Two-column proof always has two columns where one for statements and one for reasons.
Here,
is a right angle and
is a straight angle(
) . (given)
Therefore,
must be right angle. ( because,
)
Which is the required proof.
Since, In the above proof both statements and reasons both mentioned, therefore, it is the two column proof.
Note: We can also make a table which consist of two columns, in first we can mention 'statements' while in second column we can mention 'reasons'.
Hey there!
The easiest way I could think to do this is by converting your mixed number to an improper fraction and multiplying the fraction by 2, or 2 over 1.


To multiply fractions, you can just multiply the numerators and denominators and simplify, if applicable.

Since you can't simplify this fraction in its improper form, just convert it back into a mixed number.

So, your answer will be

.
Hope this helped you out! :-)
