<h3><u>The value of the smaller number, y, is equal to 9.</u></h3><h3><u>The value of the larger number, x, is equal to 12.</u></h3>
x + y = 21
x = 2y - 6
We have a value for x, so we can plug it into the original equation to solve for y.
2y - 6 + y = 21
Combine like terms.
3y - 6 = 21
Add 6 tot both sides.
3y = 27
Divide both sides by 3.
y = 9
Now that we have a value for x, we can plug it into the 2nd equation to solve for x.
x = 2(9) - 6
x = 18 - 6
x = 12
The chance of you drawing a 10 is 1/13 and times 13 is a 1/1 chance of drawing a ten
Answer: 320 inches^2
Explanation: Surface Area = 2×(7×4 + 7×12 + 4×12) = 320 inches^2
