Each lion has 1 head. The number of lion heads is L .
Each bird has 1 head. The number of bird heads is B.
The total number of heads of all species is (L + B) = 30
Each lion has 4 feet. The number of lion feet is 4L .
Each bird has 2 feet. The number of bird feet is 2B .
The total number of feet of all species is (4L + 2B) = 100
The system of linear equations is:
L + B = 30
4L + 2B = 100 .
Answer:
30
Step-by-step explanation:
1) 13.02-6y=8y
+6y=6y
13.02=14y then divide both sides by 14. you get y= .93
2) 1/5x+5=19-1/2x
-5=-5
(1/5x=14-1/2x)5
x=70-2.5x
+2.5x=+2.5x
3.5x=70 divide both sides by 3.5 and you get x=20
3) 7.3t+22=2.1t-22.2
-2.1t =-2.1t
5.2t+22=22.2
-22=-22
5.2t=-44.2 divide both by 5.2 and t=-8.5
4) (1.4+2/5e=3/15e-.8)15
21+6e=3e-12
-3e=-3e
21+3e=-12
-21 =-21
3e=-33 divide both by 3 and e=-11
5) 5(x-4)=2(2x+5)
5x-20=4x+10
-4x -4x
x-20=10
+20=+20
x=30
6) -7(3+t)=4(2t+6)
-21-7t=8t+24
+7t=+7t
-21=15t+24
-24= -24
-45=15t divide both by 15 and t=-3
7) (3/4x+6=1/3x+9)4
3x+24=1.3x+36
-1.3x =-1.3x
1.7x+24=36
-24=-24
1.7x =12 divide both sides by 1.7 and x=7.06

Answer:
Raised money = $2700
Step-by-step explanation:
Let x be the raised money.
Given:
The statement says the members used 74% of the money to buy uniforms, 18% for equipment,
Therefore, 74% + 18% = 92%
So the member used 92% of the money to buy uniform and equipment.
Remaining (100-92)% = 8% of the money for a team party is $216.
So, 8% of raised money = 216
8%
raised money = 216
![\frac{8}{100}\times x = 216](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B100%7D%5Ctimes%20x%20%3D%20216)
![x=\frac{216\times 100}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B216%5Ctimes%20100%7D%7B8%7D)
![x=\frac{21600}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B21600%7D%7B8%7D)
![x=2700](https://tex.z-dn.net/?f=x%3D2700)
Therefore, the raised money is $2700.
