Answer:
This is a ratio question. Set 16/2000 = x/5000 and solve for x. = 40 trees
Step-by-step explanation:
7/8(x-1/2)=-49/80
70/80(x-40/80)=-49/80 make all common denominator
x-40/80=-56/80 divide -49/80 by 70/80 to isolate parentheses
x=16/80 or 1/5 add 40/80 to isolate x
I'm not sure if my answer right because I was rushing but if you follow what I wrote next to the lines you should get the right answer
2/5 I think , you can double check tho
so we're trying to figure what portion of silas' slime is detergent. we know that his slime is a combo of 5 oz glue and 2 oz detergent for a total of 7 oz of slime.
what we want to find is how much of those 7 oz of slime is detergent.
quite simply 2 oz of the 7 is detergent.
to make that into a percent just divide 2 by 7.
2/7 = 0.2857
then move the decimal over two spots to get
28.57 or
D. 28.6%
just remember that percents are just how much makes up the whole.
102% of 250 = 255 Hope this helps ( :
