The equation 1.5r + 15 = 2.25r represents the number r of movies you must rent to spend the same amount at each movie store. how

EleoNora [17]

1.5r+15=2.25r
First of all, you have to arrange the numbers according to those similar to them. So that will be;
15=2.25r-1.5r
1.5r is subtracted from 2.25r because it crossed over an equality sign to get its position close to 2.25r. And when a number crosses over an equality sign, the sign on the number chages to the opposite. 1.5r has an invisible positive sign which became negative when it crossed. Anyway;
2.25r-1.5r is the same as 2.25-1.5. And that is 0.75r
Therefore;
15=0.75r
To find out what r is, you have to divide the both sides by 0.75. This is done to remove the 0.75 close to r to finally reveal what r is. Anyway;
15/0.75=0.75r/0.75
15 divided by 0.75 is 20. And 0.75r divided by 0.75 is r. So;
20=r
r=20. So the answer is 20 movies. Hope i helped. Have a nice day.

The perimeter of a square is 52 cm.<br> Calculate the area of the square

Nonamiya [84]

Answer:

$169cm^2$

Step-by-step explanation:

The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is $169cm^2$ ,

If this helped, brainliest answer would be greatly appreciated!

Sebastian was in a hotel lobby and took the elevator up 7 floors to his room. Then he took the elevator down 9 floors to the par

Aleks [24]

Answer:

Sebastian's error = 9 + (-7)

The correct expression for Sebastian's movement = 7 + (-9)

Step-by-step explanation:

Using the Lobby as a reference point

Sebastian's took 7 floors to his room

Hence, Lobby + 7 floors = Sebastian's room

Then, he took 9 floors down to the garage

Hence, Room - 9 floors = Garage

Therefore the total movement for Sebastian = Number of floors taken to his room + Number of floors taken to the garage

= 7 +(-9)

a) Sebastian's error was making the number of movements to his room negative, it is meant to be positive because he took the elevators UP

b) Sebastian's error was making the number of movements to the elevator positive, it is meant to be negative because he took the elevators DOWN to the garage

Hence, the correct expression = 7 +(-9)
