Choose the equation that could be used to find two consecutive integers whose sum is 69.

n + (n + 2) = 69

n + (n + 1) = 69

n − (n + 1) = 69

n + 2n = 69

Question

Choose the equation that could be used to find two consecutive integers whose sum is 69.

 n + (n + 2) = 69

 n + (n + 1) = 69

 n − (n + 1) = 69

 n + 2n = 69

anonymous · Answer

do you know what consecutive integers are?

anonymous · Answer

no equation for this, just make an educated guess
32 + 33 = 65 too small, try again

anonymous · Answer

try the last one ;P

solve for n first! :D

anonymous · Answer

There is one and it is one of the choices. buzzz

anonymous · Answer

hahaha @ChmE  =P

and heres my hint :)

Hint: Use the last choice and solve for n :P

anonymous · Answer

i got it its n+(n+2)=39 so the two consectuive intergers would be 33 and 34 and this equals 69

anonymous · Answer

does 33+34 = 69 ???????????????????? no

not quite... here follow this :)|dw:1355340414583:dw|
