The solution set is (7,3).
Step-by-step explanation:
Given system of equations is;
3x−2y=15 Eqn 1
y=2x−11 Eqn 2
Substituting value of y from Eqn 2 in Eqn 1
Putting x=7 in Eqn 2
The solution set is (7,3).

6x - 2y = 18
-2y = -6x + 18
y = -6x/-2 - 18/2
y = 3x - 9
comparing to y = mx + c,
m = 3,
Slope = 3
She curled an 8 inch by 10 inch rectangular piece of paper to form an open cylinder. A height of that cylinder is h = 10 in. Then 8 inches will represent the circumference of the base of the cylinder ( or the circumference of the circle, which represents the base ). Therefore: C = 2 r π, or: 8 = 2 r π. Now we can also calculate the radius of the base:
r = 8 : 2 π = 8 : 2 * 3.14 = 8 : 6.28 ≈ 1.27 in.
Answer: 8 inches will be the circumference of the base of the cylinder.
One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.
-- One leg is 3 times the length of the other leg.
-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle.
I'll bet that if you look through the choices, you'll find one there.
