Hello 9-05 and hello world,

So yesterday for math class our test was posponed, due to lack of understanding questions and how to solve them. Anyways, to help us understand the "hard" questions Mr.Backe went over questions with us, and made sure that we understand what the questions mean, and how to solve them.. Lets begin :

1. 4 - 6 = 7 +2
   ___ ______ ( Solve what you can and need to first )
   x + 2 2( x - 4 )

- 2 9
___ = ______ ( From here you can now cross multiply )
x + 2 2x - 8

-2 ( 2x + 8 ) = 9x + 18 ( Now you solve what you can and need to again )

-4x - 16 = 9x + 18 ( Then you gather all the like terms )

-16 - 18 = 9x + 4x

- 2 = 13 x
____ ____ ( Last step is to isolate the variable )
13 13

-2
_____ = x
13

1. B scored 78% on its test. B had 11 correct answers. What was the test out of?

We always start with what we know. We know that he scored 78% and got 11 right, we can make the equation and just solve for x.

78 = 11
___ ____
100 x

78x = 1100
____ ____
78 78
x = you'll get an ugly number so just round the number.

Then we did other questions, that are similar to those. So just make sure you understand if not GO TO MATH HELP PLEASE. Good luck guys!

In today's math class we were given back our Equations Test. We went over the test and Mr. Backe also gave us some more equations to solve.

Test Questions:

Equations:

For some of the equations, we had to find the common denominator and the lowest common multiple.

We also have another equation test coming up on Wednesday.

That's all we did today. THANK YOU FOR READING AND PLEASE COMMENT !
