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.
Answer:
I think if you take the two of the equations and subtract them from eachother then youll get a number being x=(blank) then just subsitute it in for the third equation and see if it works. (sorry if this doesnt help)
Step-by-step explanation:
Answer:
6 3/8
Step-by-step explanation:
FIrst, reciprocal means that you have to change the order of the fraction.
8 1/2 = 17/2
1 1/3 = 4/3
17/2 by the reciprocal of 4/3 = 17/2 by (this word means to multiply) 3/4
17/2 * 3/4 = 51/8 = 6 3/8
