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
Answer:
k=4
Step-by-step explanation:
First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.
