Answer:
Step-by-step explanation:
28=2x-9
37=2x
x=18.5
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3 of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.
Answer:
10
Step-by-step explanation:
i think its 10 maybe cuz if u see
the perimeter of a rectangular room is 52 feet. right?
then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!
now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10
