Answer:
(x, y) = (8, 2)
Step-by-step explanation:
The relevant equations are ...
3x -y = 22
x +2y = 12
__
We can eliminate y by adding twice the first equation to the second.
2(3x -y) +(x +2y) = 2(22) +(12)
7x = 56
x = 8
Substituting into the first equation gives ...
3(8) -y = 22
y = 24 -22 = 2
The first number is 8; the second number is 2.
I think 6) is 17/25, 82%, 8,5, 8/5
Answer: length is 10 feet, width is 6.5 feet
Step-by-step explanation:
I'm sure that the hypotenuse is 13 yards
Here's the formula used:
Length of Hypotenuse² = Length of side 1² + Length of side 2²
So here's how to solve this question:
12 squared + 5 squared = hypotenuse
(Then square the values)
144 + 25 = 169
Divide 169 by the square root to get the length of the hypotenuse: 13
Hope this helps!
