Answer:

(a-b) = -25

Step-by-step explanation:

(a+b) = -5

a*b=-150

So one of the letters have to be negative as you can only get a negative product from a positive and negative

There is probably a better way to do this, but I just plug in numbers that I think will work

So, (a*b) = -150, (-15*10) = -150

Okay that works so lets try the other one

(-15+10) = -5

This also works, so lets do the third one

(-15-10) = -25

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

Answer:

9+x*-7=-19

9-7x=-19

-7x=-19-9

-7x=-28

x=-28/-7

x=4

The number 4 is the required expression.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Let x be the required number.

And the given expression is the sum of 9 and the product of a number and -7 is -19

That means ,

9 + x × -7 = -19

Using PEMDAS,

9 - 7x = -19

-7x = -19 -9

-7x = -28

x = 4

Therefore, the required number is 4.

Juan have 7 bill for $1 bills.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Juan has $67 in $5 and $1 bills.

And, He has 19 bills in all.

Now, Let number of $1 bills = x

And, Number of $5 bills = y

Here, Juan has $67 in $5 and $1 bills.

So, We get;

⇒ x + 5y = 67  .. (i)

And, He has 19 bills in all.

So, We get;

⇒ x + y = 19  

⇒ x = 19 - y .. (ii)

Substitute the value of x from (ii) in (i), we get;

⇒ x + 5y = 67

⇒ 19 - y + 5y = 67

⇒ 19 + 4y = 67

⇒ 4y = 67 - 19

⇒ 4y = 48

⇒ y = 12

And, from (ii),

⇒ x = 19 - y

⇒ x = 19 - 12

⇒ x = 7
