Answer:

X = 100

Step-by-step explanation:

X + 20 over 4 = 30

1/4x + 5 = 30

-5 -5

1/4x = 25

multiply both sides by 4

x = 100

if I have to add 97 oz of algaecide to 10,000 gallons of water how much should I add if I only have 200 gallons of water

juin [17]

Answer:

1.94 oz

Step-by-step explanation:

x/97 = 200/10000

97*200 = 10,000x

19400 = 10,000x

1.94 oz

You can also do it this way:

200/10000 = 0.02

0.02 * 97 = 1.94
