Answer:
first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

Answer:
Step-by-step explanation:
In 2016 there were about 64,500 cinema screens in a country.
If about 29.9% of screens in the country were digital 3-D screens, we would determine the approximate number of 3D screens by dividing the Percentage of 3D screens by the total percentage of 100 and multiplying by the total number of cinema screens. It becomes
29.9/ 100 × 64500 = 0.299 × 64500
= 19285.5
The number of 3D screens is approximately 19286
So your answer would be 7 because if you divide 21÷3 your answer would be 7.
