AlladinOne [14]3 years ago
5 0

Answer:

A___B___C

AC = AB + BC

39 = [ 4(x+5) ] + (2x +1)

39 = (4x + 20) + ( 2x +1)

39 = 6x + 21

6x = 39 - 21

6x = 18

x = 18/6

x = 3

AB = 4( x +5) = 4x + 20 = 4(3) + 20 = 12 + 20 = 32

I hope I helped you^_^

The sum of two numbers is 65 and the difference is 13.what are the numbers?
Karolina [17]

Answer: 26 and 39

Step-by-step explanation:

Let the numbers be x and y . Also , let us take x as the larger number.

From the first statement :

x + y = 65 ...................... equation 1

From the second statement :

x - y = 13 ....................... equation 2

Solving the system of linear equation by elimination method. Let us eliminate y first , then we need to add the two equations to eliminate y , the equation then becomes

2x = 78

x =39

substitute x = 39 into equation 1 , that is

39 + y = 65

y = 65 - 39

y = 26

Therefore , the numbers are 26 and 39

Show work for repeated subtraction to divide 35÷4
Sonja [21]
35/4

You'd start by dividing 4 into 3. Since three is smaller it will not work. So you then divide it into 35. 35/4=8.75
