Opposite means add a negative sign in front of it.

The opposite of 6 is -6,

7 --> -7,

-10 --> 10.

Reciprocal means flip it.

Reciprocal of 6 is 1/6

of 7 is 1/7

of -10 is -1/10

Opposite reciprocal means add a negative sign AND flip it.

6 --> -1/6

7 ---> -1/7

-10 --> 1/10

In geometry, perpendicular lines on a graph have opposite reciprocal slopes.

A club is making posters to raise money. The printer charges a base fee of $270 and $2 per poster for supplies. A person sells e
sesenic [268]

<u>Answer:</u>

He must sell 190 posters make a profit of $300.

<u>Explanation: </u>

Given:

Base fee= $270  

Fee for supplies= $2

Cost of poster=$5

To find:

The number of posters to be sold to get a profit of $300=?

Solution:

Let the number of posters sold be n.

Now, we know that,

profit = selling price – cost price

$ 300 = $ 5 for each poster – ( $ 270 base fee + $ 2 for each poster)

300 = 5 x n – (270 + 2 x n)  

300 = 5n – 270 – 2n  

5n – 2n = 300 + 270  

3n = 570  

n=\frac{570}{3}

n = 190

sweet-ann [11.9K]

If Jey Uso was  born on a Wednesday, the day of the week that  Roman Reigns was born is Thursday.

<h3>What day of the week was  Roman Reigns born?</h3>

There are 365 days in a year when there is no leap year.

Now determine the number of years that make up 759 days: 759 / 365 = 2 years + 29 days

Now determine how many weeks are in 29 days : 29 / 7 = 4 weeks and 1 day

Thus,  Roman Reigns was born on Thursday.
