The total volume of both cubes is 108
Get the x terms by themselves on one side and a constant on the other side of the equal sign...
4x^2-8x=1 make the leading coefficient equal to one...
x^2-2x=1/4 now halve the linear coefficient, -2 in this case, square it, and add that value to both sides of the equation...-2/2=-1, -1^2=1 so
x^2-2x+1=1+1/4
x^2-2x+1=5/4 now the left side is a perfect square...
(x-1)^2=5/4 take the square root of both sides...
x-1=±√(5/4) add 1 to both sides
x=1±√(5/4)
Answer:
y=7
x=-7
Step-by-step explanation:
2(-3x - 7y )= 2(-28)
3(2x+ 3y)=3(7)
-6x - 14y = -56
6x + 9y = 21
Add the two equations
-1(0x - 5y)= -1(- 35)
5y = 35
Divide both sides by 5
y=7
Substitution
6x + 9(7) = 21
6x + 63 = 21
Subtract 63 from both sides
6x = -42
Divide both sides by 6
x= - 7
(4x - 8) = 80/2
4x - 8 = 40
4x = 48
x = 12
answer
x = 12
Answer:
85 milometers is less than 0.85 litters
Step-by-step explanation:
0.85 litters is 850 milometers or u could say 85 milometers is 0.085 litters witch means 850 milometers(0.85 litters) is more than 85 milometers or 0.085 litters(85 milometers) is less than 0.85 liters.
