Answer:
9.9375
Step-by-step explanation:
3/8[-8+16-(-2.5)]
=3/8(-8+16+2.5)
=3/8(26.5)
=9.9375
X + Y = 18
X=chickens, Y=Cows
2x + 4y = 60
Let's try 8 and 10.
16 + 40=56, no, 32+20=52, no. 8&10 do not work.
Let's try 9 and 9.
18+36=54, no. 9&9 do not work.
Let's try 11 & 7.
22+28=50, no. 14+44=58, no.
Let's try 12 & 6.
24+24=48, no. 12+48=60 YES!
There are 12 cows and 6 chickens.

Hope this helps. Plz give Brainliest! :)
The general formula: y=mx+b
(6,2) ⇒ x=6,y=2
m=3
b=?
2=3*6+b
2=18+b
b=-16
<u>y=3m-16</u>
Hey!!
here is your answer >>>
As we know, The formula for the length of a trinagle is
(1/2)(base)(height) !.
Height is 6/5 and area is 2/5, then what is the base, we will just have to substitute these values!.
which is ,
2/5 = (1/2)(base)(6/5)
2/5 = (base)(3/5)
base = (2/5)/(3/5)
base = (2/5)(5/3)
base = 2/3 ft!.
Hope my answer helps!
