Answer:
8 + j = 35
subtract 8 from both sides
j = 27
Step-by-step explanation:
10% of 35 is 3.5
20%= 7
50% = 17.5
25% = 8.75
10% of 250g is 25
10% of 350 is 35
10% of 205 is 20.5
10% of 305 is 30.5
lemme get the branliest
the first solution is 20% acid, and say we'll be using "x" liters, so how many liters of just acid are in it? well 20% of "x" or namely 0.2x. Likewise for the 60% acid solution, if we had "y" liters of it, the amount of only acid in it is 0.6y.
They would be alternate exterior so they would have to to be equal
2k + 11 = 131
-11 -11
2k = 120
