11 +5+11=27in perimeter is adding all the sides together
Answer: y = -1, y = 6 (choice D)
===========================================================
Work Shown:
y - (6/y) = 5
y*(y - (6/y)) = y*5 <<--- see note 1 below
y^2 - 6 = 5y
y^2 - 5y - 6 = 0
(y+1)(y-6) = 0 <<--- see note 2 below
y+1 = 0 or y-6 = 0
y = -1 or y = 6 which are the two answers
note 1: I multiplied both sides by y to clear out the fraction (the LCD is y)
note 2: I factored the left side by asking myself "what two numbers multiply to -6 and add to +5?" the answer to that question is +1 and -6 which helps lead to the factorization. An alternative route instead factoring is to use the quadratic formula
Answer:
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Associative property with addition</em>
<em>(a+(b+c)) = (a+b) + c</em>
A)
Given 0.85 + (0.15 +(-3)) = (0.85 +0.15)+(-3)
= 1 - 3
= -2
B) Given [(-3)+(-3)]+(-3) = ( (-3)+[( -3)+(-3))]
= ( -3 +[-3-3]
= -3 -6
= -9
<u><em>Final answer:</em></u>-
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>
