Add the two equations: 5x=10, x=2, but x-y=1 so y=1. The solution set is uniquely (2,1).
Answer:
18√2
Step-by-step explanation:
2√3 x 3√6
2 x 3 x (√6 x √3)
=> 6√18
=> 6√(3x3x2)
=> 6 x 3√2
=> 18√2
About 6.25 All you have to do is divide 16.25 by 2.6
1:2:3...total is 6
1/6 of 5 1/4 = 1/6 * 21/4 = 21/24 = 7/8
2/6 of 5 1/4 = 2/6 * 21/4 = 42/24 = 1 3/4
3/6 of 5 1/4 = 3/6 * 21/4 = 63/24 = 2 5/8
7/8, 1 3/4, 2 5/8...total = 5 1/4 inches
