Answer:
the = sign means both sides of the equation have the same value.
13×965= $12,545
each person pays $13 and 965 people come so you times them together to get the answer
We know 20% is 15
and now we find 80%
since 20% x 4 = 80%, we can multiply 15 by 4 to get 80% of 75
15 x 4 = 60
80% of 75 = 60
Δ = 1 + 4*20 = 81
x' = (-1 + 9)/2 = 4
x'' = (-1 - 9)/2 = -5
4² + 4 - 20 = 0
(-5)² - 5 - 20 = 0
Ok !
Okay so 0.08L=80mL. 8,000mL=8L. 0.8L=800 mL. And 80mL=0.08L. Hope this all helps
