The sum of three consecutive odd numbers is 159. What is the smallest of the three numbers ?

1 answer:

6 0

Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.

<h2>X + X + 2 + X + 4 = 159</h2><h2 /><h2>3x + 6 = 159</h2><h2> -6 -6 ← subtract 6 on both sides</h2><h2 /><h2> 3x = 153</h2><h2> ÷3 ÷3 ← divide both sides by 3</h2><h2 /><h2> X = 51</h2><h2> X + 2 = 53</h2><h2> X + 4 = 55</h2><h2 />

Therefore, the smallest of our three consecutive integers is 51.

Answer:

18 > 14, true

12 - 16 = -4, true

Homework = (4 + 6*2+10*3+12*2+14*4+16*2+18)/15 = 11.73
Television = (0 + 10*3+12*1+16*3+18*4+20*3)/15 = 14.8

<u>The difference:</u>

14.8 - 11.73 > 1, NOT true

True
