Answer:
length: 23 m; width: 11 m.
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:
l + w = 34
l - w = 12
Adding these together gives you ...
2l = 46
l = 23 . . . . . . divide by 2
Then the width is
w = 23 -12 = 11
The length and width are 23 m and 11 m, respectively.
(- 3/4) + (-3/8)
= (- 6/8) - 3/8
= negative 9/8
That is sort of a vague question, but in general you can:
1. Analyze the problem to identify:
a) What type of problem it is (word problem, algebra,etc.)
b) What the question is asking you (you must understand the question to do it)
2. Draw visuals (ex. venn diagram), graphs and tables to help you start the question
3. Create a plan to solve the question. For example the formulas and materials you need.
4. Try to solve the problem. This can be achieved in many ways.
5. If you are having problems, refer to the internet or ask a friend, teacher, parent or tutor.
There can be 6 teams because 2 is the lowest number that can go into both 12 and 18. (12/2) = 6...and I know (18/2 = 9) but there wouldn't be enough boys to make 9 teams
there will be 6 teams each containing (12/6) = 2 boys and (18/6) = 3 girls
