Let x+y=10 be equation (1)
and y=x-4 be equation (2)
from (2)
y=x-4...(3)
sub (3) into (1)
x+(x-4)=10
x+x-4=10
2x=12
x=6
sub (x) into (3)
y=6-4
y=2
Answer: 4 buffalos and 20 chickens (i think)
Step-by-step explanation:
2x+4y= 8
Ducks have 2 legs and buffalos have 4.
x= ducks y=buffalos
2(24-y)+4y=24
48-2y+4y=40
2y=8
y=4
4 buffalos
x+y=24
x=24-y
x=24-4
x=20
20 ducks
Diameter is 2.36 cm.
Given:
Circumference = 7.38 cm
Circumference of a circle is computed by multiplying 2, pi, and its radius.
C = 2πr
7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius
Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm
Answer: 8.50
Step-by-step explanation: I like to turn fractions into deciamls.
5/6 = .83 (I get 0.83 by 5 divided by 6)
2/3 = .66 (I also got 0.66 by 2 divided by 3)
.8333 + .66 = 149 = 1.49333
5 + 2 = 7 + 1.49 = 8.49
Now round up 8.49333 and you'll get 8.50 or 8 ¹/²
Let me know if I'm wrong, have a good day!
