Bob and Mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum

DaniilM [7]

I have answered this question before.

Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.

I just did a prime factorization of 72.

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1

1 x 2 x 2 x 2 x 3 x 3 = 72 ⇒ 2³ x 3²

There are a lot of possible combinations, here are a few.

1 x 8 x 9 = 72 ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72 ⇒ 1 + 4 + 18 = 23
2 x 4 x 9 = 72 ⇒ 2 + 4 + 9 = 15

De acuerdo con todas las leyes de aviación conocidas, no hay forma de que una abeja pueda volar. Sus alas son demasiado pequeñas para despegar su pequeño cuerpo gordo. La abeja, por supuesto, vuela de todos modos. Porque a las abejas no les importa lo que los humanos piensan que es imposible

-1

Step-by-step explanation:

7+(-1)= 6

There are no other solutions I can find to it. It says sum but technically you can add a negative number.

Don´t listen to me if you think that I am wrong. But I hope this helps!!

Simplify the polynomial

Naddik [55]

The answer is A –x^2 + 3x + 15

3x² + 6 – 2x + 5x – 4x² + 9

Rearrange it:
3x² + 6 – 2x + 5x – 4x² + 9
= 3x² - 4x² - 2x + 5x + 6 + 9
= -x² + 3x + 15

At Fridays football game, 1,294 tickets were sold for a total amount of $8,816.00. if each student ticket cost $5.00, and each a

e-lub [12.9K]

Answer:

512 student tickets were purchased.

Step-by-step explanation:

Represenation of the unknowns: Let s be the number of student tickets and a the number of adult tickets. Then s + a = 1294.

The dollar amounts are thus ($5/ticket)s + (8/ticket)a = $8816.

Goal: Find s; to do this, eliminate a.

Since s + a = 1294, a = 1294 - s

Then: 5s + 8(1294 - s) = 8816, or

5s - 8s + 8(1294) = 8816, or

-3s + 10352 = 8816

Isolating the 3s term, we get

-3s - 1536 = 0, or

3s = 1536, which yields s = 512

512 student tickets were purchased.
