Answers:ok first you have to replace the letters with the numbers.. 9x15/(2x7+1) then you need to figure out the problem that's in the brackets 2 times 7=14 plus 1=15 so you can change it to 9x15/15 9 times 15=135 divded by 15=9 So the answer is 9 Hope i helped! :) if you need some more help email me im 13 and im in grade 10
Answers:To simply is the destination of all complex problems. So if you have a part of your mathematical expression such as ( 4 + 1) it is simpler to say 5. Hence 6 x 7 - 3 x 5. It is a simpler expression. But do not try to solve it yet, it can become even simpler. Now then what is 6 x 7 It is 42 What is 3 x 5 It is 14 Now the expression is simpler 42 - 14 What is 42 - 14? Easy yes? You know the answer before you count it because it is so much simpler. The important question to ask your teacher is to teach you the order of operations. This means when you have a complex and messy expression what operation do you perform first, the multiplication, the division, or the addition and subtraction. TO get full marks you need to show each step of your simplification. To give you a heads up for next class First do all operations that lie inside brackets. This is easy because we already know that they are separate from the rest of the expression and they belong together. Working from left to right, do the multiplication. Then working from left to right do all division. Finally, working from left to right, do all addition and subtraction. It is very easy. But as I recall, my teachers made math so complicated. You may wish to ask your parents to get you a computer program to teach you. You have no idea how stupid teachers are. Also if you get the easiness of algebra you may wish to study logic later.
