During 3 days joy the cat was catching mice .Each day joy caught 3 mice more than the previous day .On the third day joy caught twice as many mice as on the first day . In total how many mice did joy catch during the three days

27

Step-by-step explanation:

Given

During 3 days the cat was catching mice

Suppose the first-day joy caught x mice

So, on the second day, it is x+3

on the third day, joy catches twice as many mice as on the first day i.e. 2x

or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day

In three day time, it is

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
