Question

I do not understand this problem i would like some help?!

Answer 1

a.) He takes down 3 bricks each minute, and it takes him 55 minutes to tear down the wall.

x = number of minutes

y = total number of bricks

3x = y

Plug in 55 for x because that is how long it took him to finish tearing down the wall

3(55) = y

165 = y

There were 165 bricks originally in the wall

b.) Your equation is 3x = y

For the table you could put whatever x values you want, I am not sure if your teacher prefers if they go in a pattern (5, 10, 15, 20 or 10, 20, 30, 40) or if they could be random inputs (10, 20, 30, 40, 50, 55) but once you choose your x inputs, you plug it into the equation to find "y"

You can go by 5's: 0,5,10,15,20,25, all the way up to 55 (which will need 3 more boxes, again idk if your teacher will mind)

For graphing, you could do for every 2 units(squares) you can go by 10's for the x-axis. And for the y-axis, for every 2 units(squares) you can go by 20's.

Answer 2

the answer to A would be 156
and I know 3 bricks per minute and it took him 55 mins. but I I'm not exactly sure what to put for the equation nor the x and Y but the numbers does have something to do with the table like
3x 3 would be bricks and X would be one minute. and 55 could be your Y on the graph but don't quote me on it tho. it's been a while. but the answer to A I'm sure of tho.
