SUMMARY

The discussion focuses on solving word problems related to mathematical expressions. The correct answers provided include: (a) n/8 for the part finished by John in n days, (b) the incorrect expression for the difference between 4k and 4h, which should be represented as 4k - 4h, (c) the clarification that a 25% salt solution in x gallons contains 0.25x gallons of salt, and (d) the representation of three consecutive integers as n, n+1, n+2. The participants emphasize the importance of understanding the context of each problem for accurate solutions.

a.if john finished the job in 8 days, what was the part he finished in n days?
b. by how much 4k greater than 4h?
c. represent the amount of salt in x gallons of a 25% by volume of salt in solution water.
d. represent 3 consecutive integers if the smallest is n.

answers

a. n/8
b. 4h+4k
c. i don't know.
d. n,n+1,n+2

can you check if my answers were correct. in c i don't understand the question. please provide explanation thanks!

d. represent 3 consecutive integers if the smallest is n.

answers

a. n/8
Yes.

b. 4h+4k
No. For example, if you were asked "How much more is 12 than 8" you would NOT answer "12+ 8= 20"!
12 is NOT "20 more than" 8!

c. i don't know.
If a solution is 25% salt then, by volume, on gallon will contain .25= 1/4 gallon of salt.

d. n,n+1,n+2
Yes.

can you check if my answers were correct. in c i don't understand the question. please provide explanation thanks![/QUOTE]
