Answer 1

Hope this is the brainliest answer and hope this helped you learn★

ANSWER:

1st one- 33
2nd one- 1

STEP BY STEP:

First let's rewrite the equation

4c + (4-3)

Now the paper told us that c=8. So let's take out the letter c in the equation and substitute it for its value.

4(8) + (4-3)

Now we solve using PEMDAS. We start with the parentheses which is (4-3).

4(8) + 1

Now lets go down to multiplication. 4(8)

32 + 1

That is our final answer for #1. 33.

Now let's move on to equation #2. Let's rewrite the equation.

16 - 3t

Just as we did before, we can substitute t for the given value. In this case, 5.

16 - 3(5)

For the next step we move on to multiplication. Let's multiply 3(5)

16 - 15

Now we have a simple subtraction problem to give us our answer! The answer for #2 is now 1.

Answer 2

The first answer is 33.
And secomd one is 1.
