So then we need to simplify the top:
Then multiply by 4 on both sides to get rid of the denominator:
Then solve for x:
So now we know that Sam needs to score a 67 on the fourth test to have an average score of 50.
<h2>Answer:</h2>
The value of t is:
t=48.8889
<h2>Step-by-step explanation:</h2>We are asked to solve the linear equation in terms of variable t.
The equation is given by:
Firstly we will solve the parentheses term in the left and right hand side of the equality as follows:
Now we combine the like terms on the left side of equality by:
Now we subtract both side of the equation by 5 to get:
Now on dividing both side of the equation by 0.90 we get:
Hence, the value of t is: 48.8889
