<u>Answer:</u>
Distance = 3r
<u>Step-by-step explanation:</u>
We are to write an algebraic expression and then simplify it for the given situation:
<em>The distance traveled by a train in three hours with a constant speed of r miles per hour.</em>
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
Answer:
Step-by-step explanation:
y=k
60=k
=k6
k=60/6 =10
This is your equation
y=10
Put the numbers in
80=10
80/10=8 then you have to square this so
=64
x=64
Answer:45
Step-by-step explanation:
Answer:
23 units
Step-by-step explanation:
Since both lines are chords, they're equal in length. This means we can set them equal to each other.
2x + 2x +2 = 15 + 8
This becomes 4x + 2 = 23.
Subtract two from each side to get 4x = 21.
Now divide by 4 to isolate x.
This makes x = 5.25.
Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units
Answer:
y = 166
Step-by-step explanation:
Find missing angle in smaller one and equate.
= 360 - 116 - 61 - 90
= 360 - 267
= 93
y - 73 = 93
y = 166
