To find the unit rate, divide total miles by number of gallons:
418 miles / 16 gallons = 26.125 miles per gallon
Round the answer as needed.

The slope-intercept form is y = m x + b y = m x + b , where m m is the slope and b b is the y-intercept. y = m x + b y = m x + b
Rewrite in slope-intercept form.
Subtract 3 x 3 x from both sides of the equation. − 8 y = 5- 3 x - 8 y = 5-3 x
Divide each term by −8 -8 and simplify. y = 3 x 8 − 58 y = 3 x 8 - 58
Rewrite in slope-intercept form. y = 38 x − 58 .
Answer:
0.25
Step-by-step explanation
There are 4 quarters in a dollar, a quarter being 25 cents. 25 x 4 = 100, a whole.
Answer:
29
Step-by-step explanation:
Let c, r, g stand for the current ages of Carolina, Raul, and Ginny. Then we have the relations ...
c = 2r
g = 3r +4
c + r + g = 52
Substituting for c and g, we get ...
2r + r + (3r +4) = 52
6r = 48 . . . . . . . . . . . . . subtract 4
r = 8 . . . . . . . . . . . . . . . divide by 8
g = 3(8) +4 = 28 . . . . . .Ginny is presently 28
On Ginny's next birthday, she will be 29.
First number = x
second number = x-3
third number = 2x
x + x-3 + 2x = 53
4x -3 =53
4x -3+3 =53+3
4x = 56
4x/4 = 56/4
x = 14
first number = 14
second number = 14-3
second number = 11
third number = 2x
third number = 2(14)
third number = 28
14 + 11 +28 = 53
53=53
