Answer: The answer equals 0
Proportional us the correct answer
Step-by-step explanation:
1) 5a+4b-3a-7b+4a
Add terms having 'a' and 'b' separately
=6a-3b
Now subtitute values of a and b :
=6(-3)-3(4)
=-18-12
=-30
2)c(6-b)-c²
=6c-bc-c²
Subtitute values of b and c:
= 6(-2)-(5)(-2)-(-2)²
=-12+10-4
=-6
3)5x²-2xy+3y
Subtitute values of x and y:
=5(-5)²-2(-5)(-2)+3(-2)
=5(25)-20-6
=125-20-6
=99
4)-k²-(7k-4m)
Subtitute values of m and k:
=-(-2)²-{7(-2)-4(4)}
=-4-(-14-16)
=-4-(-30)
=-4+30
=26
5)3(6x+5y)-2y
Subtitute values of x and y:
=3{6(3)+5(-3)}-2(-2)
=3(18-15)+4
=3(3)+4
=9+4
=13
6)5(3m-n)-4(2m-n)
Subtitue values of m and n:
=5{5(-8)-(-11)}-4{2(-8)-(-11)}
=5(-40+11)-4(-16+11)
=5(-29)-4(-5)
=-145+20
=-125

Answer:
27 gallons
Step-by-step explanation:
Our equation is: 
What do we need to find: x
We need to first find x, so lets find x first.
=> 
=> 
=> x = 27
Lets go back to our equation.
We are going to simplify this before solving this. We are going to get:
=> 18 = 18
Therefore, we found x and we checked that our x value is correct. Now, we need to find how many gallons can the container can hold.
[a = gallons can the container hold]
=> x = a
Basically that means the container can hold 27 gallons of water.
Please give me brainliest if this is helpful ;D
Y = 1/2x - 5...2y = x - 10...2y - x = -10
y = 1/3x + 6....3y = x + 18...3y - x = 18
