84 pounds on earth is about 14 pounds on the moon but to be exact it is 13.89 pounds.
Answer:
{x,y} = {8,3}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 4y = 2x - 4
[2] y = x/2 - 1
// Plug this in for variable y in equation [1]
[1] 3x - 4•(x /2-1) = 12
[1] x = 8
// Solve equation [1] for the variable x
[1] x = 8
// By now we know this much :
x = 8
y = x/2-1
// Use the x value to solve for y
y = (/2)(8)-1 = 3
The answer would be 19
Range is basically just taking the highest and lowest number which in this case is 61 and 42 and then subtracting which gives you 19. Hope this helps!
