Vanessa has taken 4 quizzes so far and her average score so far is an 88. If she gets a 100, a perfect score on the remaining two quizzes, what will her new average be?

The science test grades are posted. All students taking the test scored over 75. Unfortunately, 4 students were absent for the test and the computer listed their scores as 0 until the test is taken. Assuming that no score repeated more times than the 0's,...

Thanks

We rode past the school in our car.

4x+2(-3x+6)=10

You can add both y's together to get no y's and then solve for x after adding 7x and 4x. Then plug in the value of x into one of the equations to find y.

Since y is the equation -3x+6 you plug in the second equation into the fist equation for y.

You then multiply the equation in the parentheses by 2 and combine like variables

sorry think of it as you are adding normally with a bar on the bottom. since you have 22 negative y's you multiply the bottom number by -1 to get a positive y. Then you add the two y's together so you ELIMINATE the y's They are no longer in the problem SO...

sorry typo two negative y's
