Mr. Liu is driving with 10 gallons of gas in his tank. His car uses 1.5 gallons of gas per hour. Write the function g(h) that Mr. Liu can use to determine the number of hours, h, he can drive before his car runs out of gas.

he can drive for about 6 houres until his car runs out of gas

Step-by-step explanation:

10gallons=1.5×h

10=1.5×h

÷1.5 ÷1.5

6.6666666667=h

they will manufacture 8496 cars

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
