Answer 2

It seems like you've provided a set of equations and you're looking to solve for the variables in each equation. Let's go through each one:

A) x × 18 = 82 To solve for x, divide both sides by 18: x = 82 / 18 x ≈ 4.5556

B) 90 : Y = 30 To solve for Y, divide 90 by 30: Y = 90 / 30 Y = 3

C) 21 : x = 3 To solve for x, divide 21 by 3: x = 21 / 3 x = 7

D) Y × 6 = 42 To solve for Y, divide 42 by 6: Y = 42 / 6 Y = 7

So, the solutions are: A) x ≈ 4.5556 B) Y = 3 C) x = 7 D) Y = 7
