Answer:

<em>Grades to be scored in 3rd exam = 88</em>

Step-by-step explanation:

Given that average of 3 numbers is 85.

First two numbers are 81 and 86.

To find:

3rd number so that average is 85

Solution:

Let the third number = $x$

Formula for average is:

$Average = \dfrac{Sum\ of\ numbers}{Total\ count\ of\ numbers}$

Here, sum of numbers = $81+86+x =167+x$

Total count of numbers = 3

$85 = \dfrac{167+x}{3}\\\Rightarrow x=255-167\\\Rightarrow \bold{x=88}$

<em>Grades to be scored in 3rd exam = 88</em>

Solve for y, 2y=-4x-14

BabaBlast [244]

Hello from MrBillDoesMath!

Answer: y = 2x - 7

Discussion:

Divide both sides of the equation by 2:

2y /2 = (4x-14)/2 = 4x/2 -14/2

or

y = 2x - 7

Thank you,

MrB
