If 5x + y = 20 and 10x - 2y = 50 are two linear equations in two variables. Find the value of x and y. A. x = 1, y = 1
B. x = 2, y = 1/2
C. x = 9/2, y = -5/2
D. x = 1, y = 5/2

a negative exponent is translated as follows:

so, we have

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

he has now walked a total of what?

if i know what this is maybe i can
