The number of trucks calculated using system of equations is 30
Let :
Number of trucks = a
Number of cars = b
Charge per car = $4
Charge per truck = $6
We could form a system of equation thus:
- a + b = 200 - - (1)
- 6a + 4b = 860 - - (2)
From (1)
b = 200 - a
- Substitute b = 200 - a in (2)
6a + 4(200 - a) = 860
6a + 800 - 4a = 860
2a = 860 - 800
2a = 60
a = 30
Therefore, the Number of trucks is 30

Answer:
36.7⁰
Step-by-step explanation:
As the triangle is right angled :
tan of the angle = 24/32
tan of angle = 3/4
angle = 36.9⁰
Let's assign variables for the unknowns. Let x be the amount of total sales while x is the amount of net sales. It is called net sales because a percentage is still deducted from it. The equation will be written as:
Net Sale = Total Sales - 0.25*Total Sales
y = x - 0.25x
y = 0.75x
