Could someone please help me solve this? 3 + 5r = - 47 Thanks!

r = -10

Step-by-step explanation:

We want to isolate r on one side so we can know what it's equal to. I'll start by subtracting 3 from both sides.

3 + 5r = -47

5r = -50

Now we can divide both sides by 5 to completely isolate our variable.

5r = -50

r = -10

We can go back and check our work by replacing r with -10:

3 + 5(-10) = -47 ?

3 + -50 = -47?

-47 = -47

If you have further questions or need clarification on anything, let me know!

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
