The answer to the question
As what I can observe, the pathway can be formed with 2 right triangles. Thus, I'll get the area of the 2 right triangles and multiply its area by the paving cost per square meter.
Area of Right Triangle: ab / 2
a = 6 2/3 m ⇒ 20/3 m; b = 3m
Area of 1 triangle= (20/3 m * 3 m) ÷ 2 = 20 ÷ 2 = 10 m²
Area of 2 triangles = 10m² * 2 = 20 m²
Total cost = $40 * 20m² = $800
Answer:
40
Step-by-step explanation:
Also, you find it by multiplying.
Answer:
x=30
Step-by-step explanation:
9 - 3 = (x/5)
6 = x/5
(x/5) = 6
x = 5x6
x = 30
Check
(30/5) + 3 = 9
6 + 3 = 9
