There are some logic ways to do this, but algebraically, this is how:

x + (x+1) = 145
2x + 1 = 145
2x = 144
x = 72

So, 72 and 73

2007-04-06 06:53:59 · answer #1 · answered by Mathematica 7 · 0 2

Two unknown Consecutive Integers, so lets call them :

x and (x+1)

Since the sum is equal to 145 that means:

x + (x+1) = 145
Solve for x:

x + x + 1 = 145
2x + 1 = 145
2x = 144 // Subtracting 1 from both sides
x = 72 // Dividing by 2 from both sides
Thats one of your integers, pluging it back to the (x+1)
72 + 1 = 73

Therefore your integers are 72 and 73!

We know that they're consecutive.

We'll call one integer x, and the other x+1 (since it's the integer right after the first one, it must by definition be 1 greater)

x+(x+1) = 145

2x + 1 = 145
subtract one from both sides
2x = 144
divide by 2
x=72

So the integer x is 72, and the next integer is 72 + 1, or 73.

72 73

Easy!
The answer is 72 and 73 because they both equal 145 and they're both positive or how you like to say it "consecutive integers"
a positive number and another positive number both equal positive, so obviously the answer is 72 and 73.

im not good at explaining but i just know im right

Divide 145 by 2 and you get 72.5 SO one has to be 72 and the other 73.

let

x = the first consecutive number

x + 1 = The second sonsecutive number

145 = the sum of the consecutive numbers

- - - - - - - - -

x + x + 1 = 145

2x + 1 = 145

2x + 1 - 1 = 145 - 1

2x = 144

2x / 2 = 144 / 2

x = 144 / 2

x = 72

72 equals the first consecutive integer

73 euals the second consecutive integer

- - - - - - - - - -s-

72 & 73.

Divide 145 by 2 to get you the approx. answer.

2007-04-06 06:54:07 · answer #10 · answered by Scott H 3 · 0 0

145/2= 72.5

So they must be the two closest to this, i.e. 72 & 73

72 + 73 =145
