Question

The sum of two consecutive intergers is 153. Which equation can be used to find the first interger n?

Answer 1

Let the smaller number be 'n'
consecutive means next number = n+1
so, sum = n+(n+1)
now can you find the equation ?

Answer 2

@hartnn is right, but i would use common sense

Answer 3

like dividing 153 by 2 ??

Answer 4

i.e. guess and check
try 73 + 74, no too low

Answer 5

153/2=76.5
so, 76+77

Answer 6

math teachers like to use equations, but don't forget you are a thinking human being with a brain.
if someone asked you outside of math class to come up with two numbers whose sum was 153 and that were one apart, i am going to bet that within one minute you could come up with 76 + 77 = 153

Answer 7

let the number be x the other consecutive is x+1
so x+x+1=153
2x=152(subtract both side 1)
x=76(divide both side by 2)
so the numbers are 76 and 77 That's it!!!!!

Answer 8

ok

Answer 9

wait it has answer choices

Answer 10

A. 2n + 1 = 153 C. n + 1 =153
B. 2n = 153 D. 2n + 2 =153

Answer 11

can anyone help me yes no maybe

Answer 12

n+(n+1) = 2n+1 =153
