Set up a proportion:
The numerator represents the words in the document, and the denominator represents the seconds it takes to print the document.
You can simplify the first fraction to make multiplication easier. Divide both the numerator and denominator by 5:
Cross multiply both fractions:
Divide both sides by 132 to get x by itself:
It will take 44.54 seconds to print the 840-word document.
I would easily recommend to convert these to decimals. If you don't know how you should search it up or ask a teacher/friend. Convert 2 3/4 to .75, and then 2 1/2 is 2.50. Add 2.75 twice because he is making 2 dozen each (and a half) equals 11. Then multiply the 2.75 by .50 (6 muffins). That is 1.375. Add 11 and 1.375 equals 12.375. I'm not 100 percent sure this is correct but I hope it helps. :)
Answer:
Answer is in the photo below.
Slope= 0.1
Step-by-step explanation:
Put the 2 as an exponent of 12: log3(12)^2=log3(144)
log3(144)-log3(16)=log(144/16)=log3(9)=2
logx^2+log(x+1)^(1/2)-logy^3
=2logx+(1/2)log(x+1)-3logy
