The answer for this equation is 540!
Answer:
a. y = 265 + 5x
b. 500 = 265 + 5x
5x = 500 - 265
5x = 235
x = 235/5
x = 47
She took 47 aerobic classes.
Step-by-step explanation:
Total Cost is yearly cost + 5 into however many aerobic classes you take.
Find the number of classes by substituting values in the equation.
Answer:
It is a proportional relation.
Step-by-step explanation:
We have given that at Time (hours) = 2, Distance (miles) = 90 and at Time (hours) = 3, Distance (miles) = 135
Therefore, the speed we get from the first two row data =
miles/hr.
So, the speed is maintained through out the journey as
At t = 0, Distance = 0
At t = 2 hours, Distance = 2 × 45 = 90 miles
At t = 3 hours, Distance = 3 × 45 = 135 miles
At t = 5 hours, Distance = 5 × 45 = 225 miles
At t = 6 hours, Distance = 6 × 45 = 270 miles
Therefore, the values matches with the table.
Hence, it is a proportional relation. (Answer)
Answer:
x=1
Step-by-step explanation:
3/2+1/2x=2x
Multiply each side by 2 to get rid of the fractions
2(3/2+1/2x)=2x*2
3+x = 4x
Subtract x from each side
3+x-x = 4x-x
3 = 3x
Divide each side by 3
3/3 = 3x/3
1 =x
