Answer:
x=-7, y= -20
Step-by-step explanation:
2x - y =6
x - y = 13
when I subract (x-y =13 ) from (2x-y =6)
2x -y =6
-x +y=-13
______________
x = -7
substitute x=-7 in the second equation
-7 - y =13
-y = 13 +7
-Y = 20
Y=-20
x=-7, y= -20
A , for example 3x^2 is a monomial. the monomial has one term
We can use a factorial to solve this:
3! = 3 * 2 * 1 = 6
So, she can wear them in a total of 6 combos.
M/w=4/3
3m/4w=1
we know w=69
3m=4*69
m=4*69/3=92
92/69=4/3
