What is the value of z in the table? a 4% 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.

87.1

Step-by-step explanation:

Lets say, first number = x

Second number = 3x+7

Total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 87.1

Hope this helps!!
