How many times must he see 9 in order to cover all 72 of them ? 72/9 = 8 . He has to see 9 patients 8 times, so he has to work 3 hours 8 times. 3x8=24 hours.
Answer:
Step-by-step explanation:
Subtract 2x
from both sides of the equation.
y=8−2x
x−y=2
Replace all occurrences of y
in x−y=2 with 8−2x
.
y=8−2x
x−(8−2x)=2
Simplify the left side.

y=8−2x
3x−8=2
Solve for x
in the second equation.

y=8−2x
x=103
Replace all occurrences of x
in y=8−2x with 103
.
y=8−2(103)
x=103
Simplify 8−2(103)
.
Tap for more steps...
y=43
x=103
The solution to the system of equations can be represented as a point.
(103,43)
Answer:
steps below
Step-by-step explanation:
1. It can be formed a triangle: sum of any two sides is greater than the 3rd side
2. It can't be an obtuse triangle: 5² + 7² = 74 < 10²
the triangle is an obtuse-angled triangle if the square of the longest side (c²) is greater than the sum of the square of other two sides (c²>a²+b²)
Answer:volume of cone = 170.5 ft³
Explanation:The volume of the right circular cone can be calculated as follows:
volume =

We are given that:
diameter = 6.1 ft.......> This means that: radius (r) = 6.1 / 2 = 3.05 ft
height (h) = 17.5 ft
Substitute with the givens in the above equation to get the volume as follows:
volume =

volume = 170.477 which is approximately 170.5 ft³
Hope this helps :)
