In order for Brady to earn a B in his biology course, his test scores must average at least 80%. On the first 5 tests, he has an
larisa [96]

Hey there! I'm happy to help!

There were 5 tests needed to make an average of 77. These numbers have to add up to 385 (77×5) because that is what you divide by 5 to find the average which is 77.

Now, we want to find an average of 80 with 6 numbers. We multiply 80 and 6, showing us that the sum of these 6 numbers must be 480. Since 5 of these numbers are the same as with the 77 average, we know that one test score (the one Brady needs to get) is added to 385 to give us 480.

480-385=95

Therefore, Brady needs to earn a 95% on the last test to receive a B in the class.

A rectangle has a length of 8 and a width of x. Write a variable expression for the perimeter of the rectangle

Since the perimeter of a rectangle is equal to twice the length plus twice the width, what you want to do here is P = 2(8) + 2(x) = 16 + 2x

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
