387x 21%= 81.27 (estimate is 81.00)

x/387 = 21/100 (cross multiple)

387x21= 8127  and 100x x= 100x  (then divide each product by 100)

8127/100 = 81.27    100x/100= x

81.27=x

Solve for r 5(r-10)= -51
Sloan [31]

Answer:

r= -1/5

Step-by-step explanation:

Step 1: Remove the parentheses (5r-10= -51)

Step 2: Move the constant to the right-hand side and change the sign (5r= -51 + 50)

Step 3: Calculate the sum of -51 +50 (5r = -1)

Last Step: Divide both sides by the equation by 5 (r = -1/5)
