Question

Solve for
0.5(r +2.75) = 3


Please I really need help I’m stuck

Answer 1

r=3.25

Explanation:

3 divided by 0.5=6

6-2.75=3.25

r=3.25

Answer 2

r = 3.25

Explanation:

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

First, divide 0.5 from both sides of the equation:

(0.5(r + 2.75))/0.5 = (3)/0.5

r + 2.75 = 3/0.5

r + 2.75 = 6

Next, subtract 2.75 from both sides of the equations:

r + 2.75 (-2.75) = 6 (-2.75)

r = 6 - 2.75

r = 3.25

r = 3.25 is your answer.
