ALGEBRA B2

Simplify 11(2k)

Solution

 =11(2k)

=11 x 2 x k

=(11 x 2) x k

=(22) x k

=22k

Hence 11(2k)=22k

AVERAGE A2

Find average of 6, 8 and 7.

Solution

6 + 8 + 7 = 21

Total of numbers = 21

Given Numbers = 3

Average = Total of numbers ÷ Given Numbers

                = 21 ÷ 3   

                = 7

Hence average is 7

AREA OF PARALLELOGRAM B1

Find area of the following parallelogram.

solution

Area = base x height

         = 14 x 3

         = 42

Hence area = 42m²      

ALGEBRA B1

Simplify 10p + 5m + 2m + p

Solution

=10p + 5m + 2m + p

=10p + p  + 5m + 2m

= 11p + 7m 

Hence 10p + 5m + 2m + p = 11p + 7m

ALGEBRA A2

Simplify 10p + 5m + 2m + p

Solution

=10p + 5m + 2m + p

=10p + p  + 5m + 2m

= 11p + 7m

Hence 10p + 5m + 2m + p = 11p + 7m

ALGEBRA A1

R - 9 = 2. Find the value of  R.

Suluhu

R - 9 = 2

R – 9 + 9 = 2 + 9

R – 0 = 11

R = 11

Hence  R = 11

AVERAGE A1

Find average of 11 and 17.

Solution

17 + 11 = 28

Total of numbers = 28

Given Numbers = 2

Average = Total of numbers ÷ Given Numbers

                = 28 ÷ 2  

                = 14

Hence average is 14
