Part A:
x - total number of liters ( milk + water )
0.2 x + 1 = x
Part B :
0.2 x + 1 = x
0.8 x = 1
x = 1 : 0.8 = 1.25 lit.
Milk:
1.25 x 0.2 = 0.25 lit.

Answer:
top down: ∞, 0, 1, 0, ∞
Step-by-step explanation:
The equation will have infinite solutions when the left side and right side simplify to the same expression. This is the case for the first and last expressions listed.
2(x -5) = 2(x -5) . . . . expressions are already identical
x +2(x -5) = 3(x -2) -4 ⇒ 3x -10 = 3x -10 . . . the same simplified expression
__
The equation will have no solutions when the x-coefficients are the same, but there are different added constants.
5(x +4) = 5(x -6) ⇒ x +4 = x -6 . . . not true for any x
4(x -2) = 4(x +2) ⇒ x -2 = x +2 . . . not true for any x
__
The equation will have one solution when coefficients of x are different.
5(x +4) = 3(x -6) ⇒ 2x = -38 ⇒ x = -19
Division is just multiplication backwards, therefore it has the same rules.
Answer:
3 seconds
Step-by-step explanation:
SO if it ran 75 meters at a speed of 25 meters per second then you have to divide how many meters it ran by how many meters it took per second to find out how long the cheetah was running
75÷25=3
3 IS THE ANSWER
The price drop is 440-154=$286. This is 286/440=26/40=13/20=0.65 or 65%.
