The sum of three numbers is 24. the largest number is three times the smallest, and the middle number is four less than the largest. what are the numbers

The numbers are 4, 8 and 12.

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the smallest number be x.

So, the largest number = 3x

and, the middle number = 3x - 4

Also, the sum of three numbers be 24.

x+ 3x- 4 + 3x = 24

7x - 4 = 24

7x = 28

x= 28/7

x= 4

Hence, the numbers are 4, 8 and 12.

Small number =X

mid number = 3X-4

large number = 3x

X+3X-4+3X=24

7X-4=24

7X-4+4=24+4

7X=28

X=28/7

X=4

S=4

M=3(4) -4=12-4=8

L=3(4)=12

The numbers are 4,8 and 12

mid number = 3X-4

large number = 3x

X+3X-4+3X=24

7X-4=24

7X-4+4=24+4

7X=28

X=28/7

X=4

S=4

M=3(4) -4=12-4=8

L=3(4)=12

The numbers are 4,8 and 12

If the ratio of side lengths of similar polygons is 6:11, what is the ratio of perimeters

Answer:

6 : 11

Step-by-step explanation:

the ratio 6 : 11 applies to all linear measure in the similar polygons

Both side lengths and perimeter are linear, hence

ratio of both is 6 : 11

Estimate the sum or difference of 23/40 11/30

The least common multiple (and i apologize for my English) of 40 and 30 is 120.

23×3 69 11×4 44

-------= ------ -------= -------

40×3 120 30×4 120

69/120 - 44/120 = 25/120 witch is equal to 5/24 if you simplify with 5.
