The circumference of the tire would be: 28 x PI = 87.96 inches = 88 inches.
88 inches / 12 inches = 7.33 feet
Every revolution the tire would travel 7.33 feet.
1 mile = 5,280 feet
3 miles = 5280 x 3 = 15,840 feet total.
Divide total feet by the circumference of the tire:
15,840 / 7.33 = 2,161 revolutions.
Answer:
The system that can be used is:
Step-by-step explanation:
We have that:
x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.
Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.
This means that:
Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.
This means that

Answer:
The slope is 4 and the y intercept is -5/2
Step-by-step explanation:
8x-2y = 5
Solve for y to get the equation in slope intercept form
Subtract 8x from each side
8x-8x-2y =-8x+ 5
-2y = -8x+5
Divide by -2
-2y/-2 = -8x/-2 + 5/-2
y = 4x -5/2
This is in slope intercept form y= mx+b where m is the slope and b is the y intercept
The slope is 4 and the y intercept is -5/2
Answer:
Step-by-step explanation:
Any line has an equation ax+by+c=0 with some constants a, b and c. Because your line passes through the points (-1,1) and (3,5), you have two equations, -a+b+c=0 and 3a+5b+c=0. If you find a solution to these equations, you will find an equation of your line.
