The sum of three consecutive odd integers is at most 123. Find the pair with the greatest sum

galben [10]

Answer:

a1 = 39, a2 = 41, a3 = 43

The pair with the greatest sum is a2 + a3 = 41 + 43 = 84

Step-by-step explanation:

Let the first integer be a1 = a.

Let the second odd integer be a2 = a + 2

Let the third odd integer be a3 = (a + 2) + 2 = a + 4

The sum of three consecutive odd integers is 123.

123 = a1 + a2 + a3

123 = a + (a + 2) + (a + 4)

123 = 3a + 6

117 = 3a

a = 39

a1 = a = 39

a2 = a + 2 = 39 + 2 = 41

a3 = a + 4 = 39 + 4 = 43

The pair with the greatest sum is a2 + a3 = 41 + 43 = 84

She gave 1/3 of cookies for her husband 1/4 of the cookies to her son and 1/6 of a cookies to her neighbor she ate the remaining

beks73 [17]

She made 15 cookies

<em><u>Solution:</u></em>

Let "x" be the number of cookies she made

She gave 1/3 of cookies for her husband

Therefore,

$Husband = \frac{1}{3}x$

Find the remaining

$Remaining = x - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}$

1/4 of the cookies to her son

Therefore,

$son = \frac{1}{4} \times \frac{2x}{3} = \frac{x}{6}$

Now again find the remaining

$Remaining = \frac{2x}{3} - \frac{x}{6} = \frac{x}{2}$

1/6 of a cookies to her neighbor

$Neighbor = \frac{1}{6} \times \frac{x}{2} = \frac{x}{12}$

Now again find the remaining

$Remaining = \frac{x}{2} - \frac{x}{12} = \frac{5x}{12}$

She ate the remaining six cookies

Therefore,

$\frac{5x}{12} = 6\\\\5x = 72\\\\x = 14.4$

Thus she made approximately 15 cookies
