Which best describes how to determine the decimal number that is modeled? 58 of 100 parts have been shaded, and 58 hundredths is written as 0.058
58 of 1,000 parts have been shaded, and 58 thousandths is written as 0.058
58 of 100 parts have been shaded, and 58 hundredths is written as 0.58
58 of 1,000 parts have been shaded, and 58 thousandths is written as 0.58

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.

1,2,4,5,10,11,20,22,44,55,110,220

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
