Distance = 250 miles, time spent = 4.5 hours
AVERAGE SPEED = DISTANCE/TIME
So AVERAGE SPEED =250/4.5 = 55.55 mi/h. The closest is 56 mi/h
Answer:
1/12
Step-by-step explanation:
When you flip a coin, there are two possible outcomes. When you roll a die there are six possible outcomes. This means the chances of getting a heads is 1/2 and the chances of rolling a 2 are 1/6. To find the probability that both will occur, multiply the two probabilities: 1/6 * 1/2 = 1/12
Answer:
4.5
Step-by-step explanation:
The answer is c hope this helps
We have a system of equations 2x - 4y = 5 and 6x - 3y = 10.
We want to eliminate one variable when we add up the equations.
If we want to eliminate the x variable, we need to multiply the top, bottom or both of the equations with a number that when the equations are added together will eliminate the x variable.
Multiply the top equation by -3.
-3(2x - 4y) = 5 * -3
-6x + 12y = -15
Now when we add the two equations together, the x's will be eliminated.
-6x + 12y = -15
6x + 6y = 10
18y = -5
The x's were eliminated.
