Question

The sum of two consecutive integers is 59. Write an equation that models this situation and find the values of the two integers.

Answer 1

If we call the first integer x, then what do we have to do to x to get to the next number right after it?

Answer 2

so you have two integers. Let's call them a and b.

\[a+b=59\]

but you also know that b is the next number between 0 and 59 after a

\[b=a+1\]

now use the second equasion by substituting the value of b in the first equasion

a+a+1 = 59

simplify and calculate a = ?

Once you know a, you know b because a+1 = b = ?

Answer 3

you see the one of the problems i'm not sure

Answer 4

I just used x for the first integer, and then x + 1 for the next. The sum of these two is represented as: x + (x + 1) = 59. x + x + 1 = 59... 2x + 1 = 59. Can you do that math?

Answer 5

consecutive integers means two integers where the second is one higher than the first

x + (x+1)
or a+b where b=a+1

Answer 6

yes I can and i've been but to it but its like non of these answers add up to it these ones I have to chose from

Answer 7

What do you have as a calculated result, and what are the options?

Answer 8

I have 4 to chose from




1: n+n+1=59;n20;+1=31
2: n+n2=59;n19;2n=38
3: n+n+1=59;n=29;n+1=28
4: n+n+1=59;n=29;n+1=30

Answer 9

n+n+1 is the correct expression, so 2 is wrong already

if you work out n+n+1=59 -> 2n+1 = 59 -> 2n = 59- 1 -> 2n=58 -> n= 29
so n+1= 30

the last option is the correct one.

Answer 10

so the answer would be 4

Answer 11

like the 4th one

Answer 12

yes

Answer 13

thank you so much!!
