Answer:
A. Total number of liters = 1.25 liters
B. Milk = 0.25 liters
Step-by-step explanation:
Let
x = total number of liters ( milk + water )
Milk = 20% of x
= 0.2x
Water = 1 liter
Total number of liters = milk + water
x = 0.2x + 1
x - 0.2x = 1
0.8x = 1
Divide both sides by 0.8
x = 1 / 0.8
= 1.25
x = 1.25 liters
Total number of liters = 1.25 liters
B.
Liters of milk in the bottle = Total number of liters - liters of water
= 1.25 liters - 1 liter
= 0.25 liter
Milk = 0.25 liters
Answer:
Option c is correct !!
Step-by-step explanation:
[ Refer to the attachment ]
As y = mx + c is an equation to represent the straight line ; we equate the given line with this equation !!
Where m is slope of the line
and c is y intercept !!
We get , m = -3/2 and c = 4
Also, two perpendicular lines follows the equation :-
Where m nth is slope of nth line !!
Answer:
(52, 32 )
Step-by-step explanation:
Given the 2 equations
y = x - 20 → (1)
x + y = 84 → (2)
Substitute y = x - 20 into (2)
x + x - 20 = 84, that is
2x - 20 = 84 ( add 20 to both sides )
2x = 104 ( divide both sides by 2 )
x = 52
Substitute x = 52 into (1) for corresponding value of y
y = 52 - 20 = 32
Solution is (52, 32 )
