Distribute the two: 2x + 6 = 18
Subtract the six: 2x = 12
Divide by two: x = 6
That's your answer!
Answer:
200 minutes
Step-by-step explanation:
In order to find the range, you have to subtract the greatest number to the lowest number. In this case, 400 is the smallest number, and 600 is the greatest number. 600-400 is 200 minutes.
Answer:
its 18 trust
Step-by-step explanation:
Answer:D
Step-by-step explanation:
The diagram can be thrown out the window. All we need is to find the chance of a 5, then the chance that the second cube rolls a 5 or a 6.
The cube has 6 possible numbers. The number 5 is one of them. Therefore we have a 1/6 chance of rolling a 5.
The second cube has 6 possible numbers. Two of those are what we want. Therefore we have a 2/6 chance, or rather 1/3 chance of rolling a 5 or 6.
Combining these, we have a 1/6 chance to roll a 5, and on top of that we have a 1/3 chance to roll a number we want.
and that is our final answer.
Answer: B 0.5 kWh per day
Step-by-step explanation:
Since the graph represents the function where electricity usage in kilowatts per hour of a clock radio varies directly with the number of days it is plugged into the wall current
The constant of variations will be the gradient ( slope ) of the graph.
Gradient = (Y2 - Y1)/(X2 - X1)
Where X1 = 2, X2 = 6, Y1 = 0.5, Y2 = 1.5
Substitute all the values into the formula
Gradient = (1.5 - 0.5)/( 6 - 4 )
Gradient = 1/2
Gradient = 0.5.
Therefore, a reasonable estimate of the constant of variation is 0.5 kWh per day
