Answer: 8 7/10 hours
whole part = 8
fractional part = 7/10
========================================================
Work Shown:
x = number of hours driving
(5/6)x = total number of gallons of gas used
(5/6)x = 7 & 1/4
(5/6)x = 7 + 1/4
(5/6)x = 28/4 + 1/4
(5/6)x = 29/4
x = (29/4)*(6/5)
x = (29*6)/(4*5)
x = 174/20
x = 87/10
x = (80+7)/10
x = 80/10 + 7/10
x = 8 + 7/10
x = 8 & 7/10
This is the same as writing 8 7/10
Amy drove 8 full hours, plus an additional 7/10 of an hour.
That mixed number converts to the decimal value 8.7
Answer:
60 degrees.
Step-by-step explanation:
We use trigonometry of a right angled triangle:
Adjacent side = 20 ft, Hypotenuse = 40 ft.
cos x = adjacent / hypotenuse = 20/40 = 1/2
x = 60 degrees.
-3+5x(-3)-3=0. So -3 is the answer
200,057
This is the how write
Answer:
Step-by-step explanation:
So all you have to do to find the slope and y intercept in that equation is look at which number is "with" the x and which is added on.
In any equation written in slope formula or y=mx+b, we can say that m = slope and b = y-intercept
So in this case we have y=-1/6x + 10
That means that m = -1/6 and b = 10
So:
Our slope is -1/6 and our y-intercept is 10.
