10500 people visited an art gallery in 2002.This was an increase of 25% on 2001.How many visitors were there in 2001?

Alenkasestr [34]

There were (10500/1.25) = 8400 visitors in 2001.

Explanation:
An increase of 25% means multiplying by 1.25. So, if the visitors from 2001 are multiplied by 1.25, then the result is 10500. Thus, the amount from 2001 was 10500/1.25=8400

Answer:

Mom === 10.25

Daughter === 3.25

Step-by-step explanation:

open the bracket which will give you 7+x=20+5x.

collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25
