Answer:
x=2
Step-by-step explanation:
-x+5=-11x+25
add +x on both sides -11x+x =-10x
-10x+25=5
subtract 25 on both sides
you get -10x=-20
x=2
The number of possible outfits would be 168 outfits. YOu can mix and match up to 168 number of outfits from these set. This is an example of counting principle. In this principle, one event has n possibilities then a second independent variable have m outcomes. Then, the total possibilities would be n times m.
Y directly proportional to WX and inversely to Z.
Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.
k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The <span>equation that models the relationship will be;
Y = 0.8(WX/Z)</span>
You would use the equation
F+V=E+2
The should be 158 ways, because 9*8+8*7+6*5=158.
