A4% peroxide solution is mixed with a 10% peroxide solution, resulting in 100 l of an 8% solution. the table shows the amount of each solution used in the mixture. what is the value of z in the table?

its 8

Step-by-step explanation:

100x0.08=8

plus i took the test on edg -_-

Step-by-step explanation:

Let x represent the amount of 4% solution and y represent the amount of 10% solution.

⇒ x + y = 100 ..................(1)

x liters of the 4% solution gives us the expression 0.04·x

y liters of the 10% solution gives us the expression 0.10·y

100 L of the 8% solution gives us 0.08 × (100) = 8

⇒ 0.04·x + 0.10·y = 8 ...........(2)

This gives us the system of equations (1) and (2)

To solve this, we will use substitution.

Substituting x = 100 - y from equation (1) into equation (2). We get,

Substitute this value of y into the first equation:

y=1/4x-4

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
