Answer:

n=-3

Step-by-step explanation:

11(n – 1) + 35 = 3n

expand left side

11n-11+35=3n

Add-11 to 35

11n+35-11=3n

11n+24=3n

subtract 24 from both sides

11n+24-24=3n-24

11n=3n-24

subtract3n from both sides

11n-3n=3n-24-3n

8n=-24

divide both sides by 8

8n/8=-24/8

n=-3

olchik [2.2K]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.

The numerator is the number above. While the denominator is the number below

an example of a fraction = $\frac{4}{5}$

4 is the numerator while 5 is the denominator

In this question, the numerator would be the number of times she walked to school in march(16). While the denominator would be the number of school days in March

$\frac{16}{24}$
