Let's first denote the intersection point of diagonals with O. In this parallelogram, we can observe that ΔAOB is congruent to ΔCOD because of AB=CD and the angles ∠BAO and ∠OCD are equal (They are alternate angles). According to the rule of congruency, 3x=4x-5 and x=5
One possible solution is 10 hours of tutoring and 3 hours of landscaping.
<h3>
Inequality</h3>
Inequality is an expression used to show the non equal comparison of two or more numbers and variables.
Let x represents the number of hours tutoring and y represents the number of hours landscaping
From the question, we form the equations:
- x + y ≤ 13 (1)
- 18x + 9y > 180 (2)
A possible solution is (10, 3)
One possible solution is 10 hours of tutoring and 3 hours of landscaping.

The total cost of a cake that serves 20 people is $35.
<u>Step-by-step explanation</u>:
- Total cost = y
- Number of additional servings = x
- The number of additional servings = 20 - 12 = 8. (x=8)
<u>The equation can be formed as</u>:
- Total cost = basic cost + (No. of additional serving
cost per additional serving) - y = 25 + x1.25
- Substitute x=8 in the above equation
- y = 25 + 8(1.25)
- y =25+10
- y = 35
Therefore, the total cost of a cake that serves 20 people is $35.
