Answer:

Step-by-step explanation:
Let
be the number of gallons so
is the number of miles traveled per
gallons.
We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by
, his car will travel a total distance of 25g (where g is the number of gallons.
We also know that the total distance is given by
, so we can put the two expressions together to get our function:

Let's check:
- If he uses 1 gallon (g=1), so

miles
He will travel 25 miles with one gallon.
- If he uses 2 gallons (g=2), so


He will travel 50 miles with two gallon.
Dividing by a half is the same as multiplying by two. 3/4 multiplied by 2 is

or, in improper fraction form

or, in decimal form, 1.5
We have been given volume of the cylinder which is 536.94 cubic inches. Now question says to find the radius of the cylinder.
Then we need to use formula of volume of cylinder which is given by :

We see that there are three unknown values in the formula: {volume, radius-r, height-h}
So to find any one of them we must know other two values.
Volume is given but height is missing. So just for explanation i'm going to use height of the cylinder h= 19 inches
Now plug the value of volume and height in above formula





take square root of both sides
3=r
Hence radius of the cylinder is 3 inches.
Answer:
x=-12
Step-by-step explanation:
4x-2x-2=3x+10
2x-2=3x+10
+2 =3x+12
2x=3x+12
-3x=12
-x=12
x=-12
