Suppose you are building a brick border for a garden by stacking rows of bricks on top of each other. if the height of each brick is 2.5 inches an r represents the number of rows, which algebraic expression would represent the height of the brick wall? explain why it's 2.5r

A single row of bricks is 2.5 inches tall. if another row is stacked on top of the first row, the total height would be 5 inches. R represents the number of rows and 2.5 represents the height of the bricks, using the equation 2.5r takes the total amount of rows and multiplies it by the height of the bricks to give you the  total height of the bricks.

Math is a complex, but faster way of doing addition. If a single row is laid the total height would be 2.5 inches, if another row is laid on top another 2.5 inches is added to the total height which would equal 5, the equation 2.5r takes the amount of rows and uses multiplication to quickly add up the total height of the bricks, so it isn't necessary to add up each individual row's height.

So i wrote so much, I am trying to explain as thoroughly as possible.  

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
