expression is
2(n-11)
If a comma were written after the word NUMBER,it would be
(2n)-11
Is it a multiple choice question?
Answer:
D is the answer
Step-by-step explanation:
We want a mixture of low-fat and whole milk to equal 32ounces
Therefore, we know one equation is:
l + w = 32
That 32 ounce mixture should be 2% butter fat
So the amount of butter fat we want is
2% of 32 = 0.64 ounces
At the same time, this mixture contains low-fat and whole milk, which contain 1% and 3.25% butter fat respectively.
therefore, the butter fat in low-fat and whole milk is 0.01l and 0.0325w respectively.
The coefficients are just the percentages in decimal form
Due to the law of conservation of mass,
The addition of these two should yield the final amount of butter fat, meaning the other equation is:
0.01l + 0.0325w = 0.64
Answer:
Step-by-step explanation:
5/9m=15
9/5x5/9 cross that out and you have to do 15/1x9/5 which is 3/1x9/1 which is 27 muffins.
multiple 9/5 by 5/9 because of the recipricol which evens out that number because it becomes whole. then do the same thing to the 15 and you simplify both the fractions then multiply which creates 27, or just look at 5/9 and 15/x 15 divided by 5 is 3 and 3 times 9 is 27 tada!!
