You have to defeat the world 5 boss as mini Mario and Mario will then go into the small opening at the bottom. You will then be at world 7.
thanks, but that's not the quesstion. getting to worl 7-A not world 7 :(
beat level 7a
To get world 7 you have to get the cannon, and to do that you have to either beat certain levels or get star coins.
7a
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19

7a 7a * 4 = 28a 7a * 7b = 49ab
7a+a=8a
-7a + 3a = -4a
It is: 7a/5xy
7 x a is written as ' 7a ' In algebra Plus is shown as ' a + b ' Minus is shown as ' a - b' Multiplication is shown as 'ab' . NEVER a x b , as the 'x' may be confused with an unknown value. Division is shown as ' a/b ' , like a fraction. e.g. 6a^(2) + 5b - 2c/3 means Six multiplied to 'x' and them multiplied to 'x' again (squared). Then you 'add' five multiplied to 'b' , then you subtract two multiplied to 'c' and the whole '2c' is divided by '3'. The divisional three only refers to the '2c'. If you wanted to divided the whole expression by '3' , then you insert brackets. [ 6a^(2) + 5b - 2c ] /3 Note the position(s) of the 'square brackets'.
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
The GCF is 7a.
