Answer:
x = 2
y = 7
Step-by-step explanation:
5x+2y=24 -------------->equ 1
8x+2y=30 -----------> equ 2
equ 1 - equ 2 =====> -3x = - 6
x = -6 / -3 = 2
x = 2
Put x = 2 in equ 1,
5*2 + 2y = 24
10 + 2y = 24
2y = 24 - 10
2y = 14
y = 14/2
y = 7

Answer:
14.14
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(10 - 20)² + (25 - 15)²
√(-10)² + (10)²
√(100) + (100)
√200
= 14.14
