Now I don’t know how to do this but I would recommended a tutor for you
Answer:
Either 3/80 grams or 0.0385 grams
Step-by-step explanation:
1 tablet = 1/40 of a gram
1/40 of a gram = 1 ÷ 40 = 0.025 grams
1 tablet = 0.025 grams
1.5 tablets = x
1/1.5 = 0.025 / x Cross multiply
x*1 = 0.025 * 1.5 Combine the factors
x = 0.0375 grams Convert to a fraction
0.0375 = 3/80
Well we know the algae doubles three times.
So take 50 x 2 = 100
take 100 x 2= 200
200 x 2 = 400
So the answer is A
(2/3x + 2 - 1/6x + 4) • 1/5 ÷ 1/5
(1/2x + 6) • 1
1/2x + 6
