So, (12x) / 12 - (8y) / 12 = 3 / 12;
Then, 12x - 8y = 3;
8y = 12x - 3;
y = (12x)/8 - 3/8;
y = (3x)/2 - 3/8;
y = (3/2)x - 3/8;
The slope is 3/2.
C all real numbers are the same
Hope that's right
You spent $50 on supplies for the bake sale Each item sold for $2. After the sale , you had a profit of $180. How many items did you sell ?
÷ = ÷
The solution of the system is:
Given system of equations is...
Here we will use substitution method as is already isolated in equation (2). So, substituting into equation (1) , we will get...
Plugging the value into equation (2)....
So, the solution of the system is:
The area of the cross section of a sphere at the largest point is 100π square miles. what is the total surface area of this sphere? leave your answers in terms of π.
The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= Where r is the radius of the circle.
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
The total surface area of this sphere is 400π .

The equation of the line that has a slope of 1/4 and a Y intercept of -3.
The standard equation of straight line in the slope-intercept form is given by the formula
where m is the slope of the straight line and b is the y-intercept.
Substitute the given values we get
Hence the equation of the line that has a slope of 1/4 and a Y intercept of -3 is
Hey there! :)
1) n + 5(n - 1) = 7
n + 5n - 5 = 7
Add 5 to both sides,
n + 5n - 5 + 5 = 7 + 5
n + 5n = 12
6n = 12
Divide both sides by 6.
6n ÷ 6 = 12 ÷ 6
n = 2
2) -4(r + 6) = -63
-4r - 24 = -63
Add 24 to both sides.
-4r - 24 + 24 = -63 + 24
-4r = -39
Divide both sides by -4.
-4r ÷ -4 = -39 ÷ -4
r = 39/4
~hope I helped~
