I believe looking at a weird perspective the answer would be 12 females. :)
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
Answer:
Step-by-step explanation:
um
y= 1.25x+6.75
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.
