3 0

Answer:

y=0.8*x -19

Step-by-step explanation:

y-5=4/5(x-30)

5*(y-5)=5*(4/5(x-30))

5y-25=4x-120

5y=4x-120+25

5y=4x-95

y=(4/5)*x -19

y=0.8*x -19

ArbitrLikvidat [17]

Hello from MrBillDoesMath!

Answer:

.08%

Let the percent be denoted "p". Then

2000 * p% = 160 =>     ( as p% = p/100)

2000* p/100 = 160 =>

20p = 160 =>

p = 8 or .08%

Me.Durham is contemplating which chauffeured car service to the airport. The first costs $30 up front and $3 per kilometer. The
Semmy [17]

Answer: 45 dollars and it was a distance of 5 kilometers

Step-by-step explanation: What i did was start with 30, then keep adding 3 till i got the a multiple of 5.

30 + 3 = 33

33 + 3 = 36

36 + 3 = 39

39 + 3 = 42

42 + 3 = 45

So already i know that it is 5 kilometers, because i added 3 to 30 five times.

No i will do that with the second company

20 + 5 = 25

25 + 5 = 30

30 + 5 = 35

35 + 5 =  40

40 + 5 = 45

That is also 5 kilometers, because i added 5 to 20 five times. I also know they are the same price, because they both added to 45 dollars.

Thats how i solved it.

I really hope that helps!
