3. The sum of two numbers is 30 and their difference is 12. Find the two numbers.

Answers

Answer:

I don't know is it 12 and 16 I'm not sure

Answer:

The two numbers are 21 and 9

Step-by-step explanation:

Let the two numbers be a and b

The sum of these numbers is 30

a+b=30

The difference between these numbers is 12

a−b=12

                             ―――――――――

I.  You can solve this by logic.

If the two numbers were exactly equal, then they would both be 15.

15+15=30

But the difference would be 0, not 12

So if you lowered b by one point, and added that to a, then the two numbers would be 16 and 14, and the difference would be 2.

So you can see that for every point you subtract from b to add to a, you increase the distance between them by 2

So, by logic, you need to subtract 6 points from b and add them to a to create a difference of 12

(15+6) minus (15−6) gives a difference of 12

.m21.....−mm∩9       =  12

Answer:

The two numbers are 21 and 9

                   ―――――――――

II.  You can solve this by math

These are simultaneous equations, so you can solve them by math.

.a+b=30

.a−b=12

2a +0=42

The Jackson family went to soups and wiches and bought four sand which sand three bowls of soup for $27. The frank family went to soups and wiches and bought one bowl of soup and five sandwiches for $25.50. Let w represent the cost of the sandwich CNN es and a represent the cost of a bowl of soup. Identify which system of equations represents the situation.

Answers

Answer:

4w + 3c = $27

5w + c = $25.50

Step-by-step explanation:

Let us assume the w represent the cost of the sandwich

And, the c represent the cost of the bowl in a soup

Now the equations are

4w + 3c = $27

5w + c = $25.50

These two should be the equations that represent the situation

Step-by-step explanation:

माना दो क्रमागत धनात्मक पूर्णाक x और (x + 1) हैं |

इसलिए...

प्रश्नानुसार,

x + (x + 1) = 145

2x + 1 = 145

2x = 144

x = 144/2

x = 72

x + 1 = 72 + 1 = 73
