pashok25 [27]

Answer:

The fraction is 470/1000, which can be simplified to 47/100, and that is 47%.

Basically you take what is asked for and you divide it by the total amount.

Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
m_a_m_a [10]

Answer:

x=2, y= 4

Step-by-step explanation:

Equation 1 is 2x-4y = -12

Equation 2 is 2x+y = 8

Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).

Simplifying we get -5y = -20 and y =4

Substituting y =4 into original equation back we get 2x -4(4) =-12

This equals 2x -16 =-12 and 2x = 4 and x =2
