I wasn't in class so I need help solving the inequality 7/10n+14<49
NikAS [45]

Answer:

n<50

Step-by-step explanation:

7/2*5n + 14<49

7n/2*5+14<49

(7n)+(2*5)14/2*5 <49

7n+10*14/2*5 <49

7n+140/2*5 <49

7n+140/10 <49

7n+140 < 10*49

7n+140 < 490

(7n+140)+(-140)<490+(-140)

7n+140-140<490-140

7n<350

7n/7 < 350/7

n<2*5^2*7/7

n<2*5^2

n<2*25

n<50

Henrietta solved a rational equation by multiplying both sides by 3x^{2}(x+2) .She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.

Henrietta can have got rid of denominator and then use the distributive rule .

So the first option

A:She could use the least common multiple of the denominator is right
