Mr Taylor arranges some chairs in row. He puts the same number of chairs in each of 7 rows and put 7 chairs in the last row. He sets up 70 chairs. How many chairs does he put in each of the 7 equal rows?

9

Step-by-step explanation:

Let the number of chairs in each of the seven rows be X.

As no of rows are 7 then total number of chairs in those seven rows will be

7 times of the number of chair in each row(which is X)

Thus, total number of chair in seven rows = 7X

no of chairs in last row = 7

Total no. of chair = total number of chair in seven rows  + no of chairs in last row

Total no. of chair = 7X + 7  equation A

It given that total no of chair is 70

thus equation will be equal to 70

balancing equation A with 70 we have

7X + 7 = 70

=> 7X = 70 - 7

=> 7X = 63

=> X = 63/7 = 9

Thus number of chairs put in each of the seven row is 9.

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
