(13/20) • 100 = 65%
65% of the can are recycled.
Answer:
22.5
Step-by-step explanation:
2.5/100= 0.0250
0.025 x 900 = 22.5
X^2+5x=2
you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.
Your answer is then
x=-5/2+-√33/2
X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
