There are several theorems that can be used to prove parallel lines
For the given information, the best theorem is <em>(d) converse alternate exterior angles theorem</em>
In plane geometry, the converse alternate exterior angles theorem implies that:
- For any two lines, that is cut through by a transversal
- If the alternate exterior angles are congruent
- Then the lines are parallel
In the given diagram (see attachment)
- The transversal is line m
- The parallel lines are line j and line k
- The alternate exterior angle on both lines is 93 degrees
Because
<em>93 degrees = 93 degrees</em>
Then, the angles are parallel based on <em>(d) converse alternate exterior angles theorem</em>

<em>x</em> = liters of 40% solution, which contributes a total of 0.4<em>x</em> liters of acid
<em>y</em> = liters of 30% solution, which contributes a total of 0.3<em>y</em> liters of acid
The chemist wants to end up with 50 liters, so
<em>x</em> + <em>y</em> = 50
and 36% of this -- 0.36 (50 liters) = 18 liters -- is acid, so that
0.4<em>x</em> + 0.3<em>y</em> = 18
Solve for <em>x</em> and <em>y</em> :
<em>y</em> = 50 - <em>x</em>
0.4<em>x</em> + 0.3 (50 - <em>x</em>) = 18
0.4<em>x</em> + 15 - 0.3<em>x</em> = 18
0.1<em>x</em> = 3
<em>x</em> = 30
<em>y</em> = 20
The journal entry to record this transaction consists of a: debit of the purchases account for $21400 and credit the accounts payable account for $21400
<h3>How to enter a transaction in a journal?</h3>
We are told that a company purchased $21,400 of supplies on credit.
Now, it is vital to note that in a journal, there is the credit column and also the debit column.
Now, the way we carry out recording the Journal Entry for a Credit Purchase is that;
When a business purchases goods or services on credit, the business will then debit the purchases account, which will increase the business’s assets.
The business will also credit the accounts payable account, which will increase the business’s liabilities.
Thus;
The journal entry to record this transaction consists of a: debit of the purchases account for $21400 and credit the accounts payable account for $21400
