Answer:
For every 64 miles, she uses 2 gallons of gas. So the answer can be 64:2 or 31:1

Answer:
D
Step-by-step explanation:
ABC are all less than -5
A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
Answer:
Option C is correct.
Step-by-step explanation:
The given equation or function is linear if the variables x and y have degree zero or 1.
The given equation is 5x^4+5y =9
here x has degree =4 and y has degree = 1, but for linear equation both x and y variables must have degree zero or 1.
So, Option C is correct.
Answer:
y=3x--3
