How many weeks are in 5 years

Answers

- -- There are 260.714 weeks total in 5 years.

52*5=260

This is because you have 52 weeks in a year and 55 years so you multiply.
52 weeks per year x 5 years = 260 weeks

What is the answer for -|-5x(-7)|​

Answers

\huge\boxed{-35}

When you multiply a negative number by another negative number, you get a positive number. So: -|-5(-7)|\ =\ -|5(7)|

Multiply. -|35|

Absolute value just finds a numbers distance from zero, or makes the number positive. 35 is already positive, so just leave it. \boxed{-35}

The solution to the absolute value function -|-5 · (-7)| is equal to -35.

How to algebraically determine the solution to the absolute value function?

In Mathematics, an absolute value function is a type of function that is composed of an algebraic expression, which is placed within absolute value symbols and it typically measures the distance of a point on the x-axis to the x-origin (0) of a cartesian coordinate such as:

|a - 4b|

Based on the information provided above, we can logically deduce the following absolute value function;

-|-5 · (-7)|

-|35|

-35

Mia 77 pieces of gum playing hoops at her school's game night. later she gave three to each of her friends. she only has five remaining. how many friends does she have?

divide by -3 on both sides to get x by itself : x = 24

The answer is that Mia has 24 friends (x = 24)
Mia has 24 friends. the answer is 24
