2x + 3x + 5x = 180
10x = 180
x = 18
2x = 36, 3x = 54, 5x = 90
They add up to 180 (definition of sum of angles of a triangle.)
Answer:
y=C+a
Step-by-step explanation:
Add a to both sides
C+a=y
Tank diameter = 1m
radius = 0.5m
height = 2m
Volume of tank of truck = πr²h = 3.142 * 0.5² * 2 = 1.571m³ = 1571 litre
Volume of tank to be filled = 890,000 litre
no. of trips = 890000/1571 = 566.52 ≈ 567 trips
Answer:
Step-by-step explanation:
x^2-16x+60
(x-6)(x-10) factor the equation
x-6=0
x=6
x-10=0
x=10
