Answer:
-2 5/9
Step-by-step explanation:
w +(-x) -2/3 = w -x -2/3 = -5/9 -4/3 -2/3
= -(5/9 +4/3 +2/3) = -(5/9 +(4+2)/3) = -(5/9 +2)
= -2 5/9
Answer:
50%
Step-by-step explanation:
Percent change = [(63 - 42) / |42|] x 100 = [(21) / 42] x 100 = 50 % (increase)
Where: 42 is the old value and 63 is the new value. In this case we have a positive change (increase) of 50 percent because the new value is greater than the old value.
25% of 80 is 20.
80*1.25 is 100.

Answer:
<em>x = 0 </em>
<em>y = 2</em>
<em>z = -3</em>
Step-by-step explanation:
x-y-2z=4 (1)
-x+2y+z=1 (2)
-x+y-3z=11 (3)
(1) + (3) = x-y-2z + (-x)+y-3z = 4+11
= -5z = 15
-> z = -3
(1) + (2) = x - y - 2z + (-x) + 2y + z = 4+1
= y-z = 5
= y- (-3) = 5
-> y = 2
(1) = x-y-2z = 4
= x - 2 - 2 * (-3) = 4
-> x = 0
