Darren wins a coupon for $4 off the lunch special for each of five days he pays $75 for his 5 lunch specials write and solve an
Valentin [98]

The original price for one lunch special is $19.

<em><u>Explanation</u></em>

The original price for one lunch special is  'p'  dollar.

He wins a coupon for $4 off for each of five days. That means , <u>he needs to pay (p-4) dollar each day</u>.

So, the total amount needed to pay for 5 days = 5(p-4) dollar

Given that, <u>he pays $75 for his 5 lunch specials</u>. So the equation will be.....

5(p-4)= 75\\ \\ 5p-20=75\\ \\ 5p= 75+20\\ \\ 5p= 95\\ \\ p=\frac{95}{5}=19

So, the original price for one lunch special is $19.

1. I feel the need to explain things first before I write the numeric value. 
   Let x be the total number of students in the school. 25% of this value is given to be 35.
                        (0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.

2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52 
                              2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.

What transformation maps the preimage (red) onto the image (blue)?
Dominik [7]

Answer:

Rotate counter clockwise about the center point 180 degrees

Step-by-step explanation:

You can use transformations to preserve shape and size but move a shape or change its position. Transformations include:

  • reflection - a flip across an axis
  • rotation - a turn around a point
  • translation - a slide a specific distance and direction

To map the red into the blue, you can rotate it counter clockwise about the center point which the red and blue shapes share 180 degrees. It will land exactly on the red.
