Answer:
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions
Step-by-step explanation:
Let
Number of multiple-choice questions = x
Number of open-ended questions = y
x + y = 38 (1)
4x + 20y = 200 (2)
From (1)
x = 38 - y
Substitute x = 38 - y into (2)
4x + 20y = 200
4(38 - y) + 20y = 200
152 - 4y + 20y = 200
- 4y + 20y = 200 - 152
16y = 48
y = 48/16
y = 3
Substitute y = 3 into (1)
x + y = 38
x + 3 = 38
x = 38 - 3
x = 35
Number of multiple-choice questions = x = 35 questions
Number of open-ended questions = y = 3 questions

Subtract 70 from 180, giving you 110. Divide this by 2. That’s how you get the measure of angle A and angle B.
<em>Question # 4</em>
<em>Answer:</em>
<em>Total number of cameras left to bid on = 3/5</em>
<em>Step-by-step Explanation:</em>
<em>To determine:</em>
What fraction of the total number of cameras is left to bid on?
<em>Solution Steps:</em>
- Total number of antique cameras contributed by a local shop = 10
- The number of cameras accepted for bids = 4
Total number of cameras left to bid on = 10/10 - 4/10
= 6/10
= 3/5 ∵ As 6/10 = 3/5
<em>Hence, total number of cameras left to bid on = 3/5</em>
<em> </em><em>Question # 5</em>
<em>Answer:</em>
<em>The remaining portion of tickets = 17/100</em>
<em>Step-by-step Explanation:</em>
<em>To determine:</em>
<em>What portion of the tickets remain?</em>
<em>Solution Steps:</em>
- The total number of tickets = 100
- The number of tickets that were sold in first week = 83
The remaining portion of tickets = 100/100 - 83/100
= 17/100
<em>Hence, the remaining portion of tickets = 17/100</em>
