d =st
distance = speed * time
10 = 4.5 * t
divide each side by 4.5
10/4.5 = t
100/45 = t (can't have a decimal in a fraction so I multiply by 10/10)
divide top and bottom by 5
20/9
2 and 2/9 hours
to get minutes multiply 2/9 by 60
2/9 * 60
120/9
13 3/9
13 1/3 minutes
2 hours 13 1/3 minutes
to the nearest minutes
2 hours 13 minutes
Answer:
y = 1/2x + 0
You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.
There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help
Answer:
x= 51
Step-by-step explanation:
-17=x/-3
(-3)-17=(x/-3)(-3)
51=x
Multiply the denominator of the fraction on both sides of the equation to isolate the variable.
Take the root of both sides and solve.
