In what proportion should water and milk be mixed to reduce the price of milk from Rs 5 per liter to Rs 4 per liter?​

Mathematics

Answer:

4:1

Step-by-step explanation:

Let us assume that the cost of water is free, that is Rs.0.

Let x represent the number of liters of milk, y represent the number of liters of water and z represent the volume of the mixture in liters, hence:

z = x + y            (1)

Milk cost Rs.5 per liter, water cost Rs.0 per liter and the mixture cost Rs.4 per liter. Therefore:

5x + 0(y) = 4z    (2)

Substituting z = x + y in equation 2 gives:

5x + 0(y) = 4(x + y)

5x = 4x + 4y

5x - 4x = 4y

x = 4y

x / y = 4 / 1

x : y = 4 : 1

The proportion in which the milk is to be mixed with water is 4 : 1, that is 4 liters of milk per 1 liter of water

How can you solve this step by step?<br> 812 divided by 12?
makkiz [27]

Answer:

How I answered this was

Line up 812 divided by 12

So 81 divided by 12 = 72

Subtract 81 - 72

Which would equal 9

then bring down the two in 812

Which would make it 92

Then divide that by 12

which would equal 84

the subtract 92 - 84

that would equal 8

put a decimal then bring down a 0

that would be 80 then divide 80 by 12

that would be 7 which would equal 8 again

so our answer would be 67.6 continuous.

11r+7s help me please
Maru [420]

Answer: First term = 11r and  second term= 7s

The coefficient in first term = 11

The coefficient in second term =7

Step-by-step explanation:

The given expression 11r + 7s is with two terms i.e. a binomial expression with variables r and s

Here the first term = 11r

And the coefficient of r in term =11

The second term= 7s

The coefficient of s in second term=7

The coefficients are the numbers that multiply the variables .

The teacher does not have to spend all $36. Write an inequality relating 36 and 9 (7 - x) representing this situation. (Copy/pas
kotykmax [81]

Answer:

<h3>9(7-x) < 36</h3>

Step-by-step explanation:

From the question, we are to relate the amount the teacher spent to the expression 9(7-x).

Since the teacher does not have to spend all the $36, this means that he spent amount less than $36 but not equal to $36. Hence the best inequality sign that relates both expression is a less than sign (<) as shown;

9(7-x) < 36

hence the required inequality is 9(7-x) < 36
