i started by comparing 2 statements.

92 = beetle + beetle + beetle + apple

64 = beetle + beetle + apple

so one beetle = 92-64

=28

(52-28)÷3=8

so one apple = 8

37-28-8=1

so gear = 1

Chapter 4: Algebra Puzzle

First, I solved the positive answer which is:

57÷3=19

so an apple = 19

next, we solve another one:

(23-19)÷2) = 2

so an umbrella = 2

Lastly, we solve another one:

19-2-2= 15.

so a star = 15.

Txtbk Question (pg 9 ques #25 and #26)

The Prime factorisation of a number is 2^4 X 3^5 X 7^2 X 11.

Write down 3 factors of the number that are greater than 100.

(Hint: 16 X 11 = 176, which is a factor.)

answer: 144, 147 and 198

solution: there are a lot of answers for this question. I came out with these answers through multiplying the factors.

144 --> 2^4 x 3^2

147 --> 3 x 7^2

198 --> 11 x 3^2 x 2

The Prime factorisation of two numbers are 2 X 3^2 X 7^3 X 13 and3 X 7^2 X 13^3 X 17 .

Write down 3 common factors of the numbers.

answer: 3, 7 and 13

solution: the common prime factors in both equations are 3, 7 and 13. since they are the same factor in different equation, the equation's answer will surely be able to be divided by the same factor.
