Question Find the equation that gives the number of bricks remaining in a pile of 40 bricks after removing 3 per week for 5 weeks. Equations: b=40−9b=40-9, b=40−3(5)b=40-3(5), b=40+3(5)b=40+3(5)

Studdy Solution

STEP 1

Assumptions1. The initial number of bricks is40. . You remove3 bricks per week.
3. You want to know the number of remaining bricks after5 weeks.

STEP 2

The number of bricks removed each week is. So, the total number of bricks removed after5 weeks would be the number of bricks removed per week multiplied by the number of weeks.
Bricks removed=Number of bricks removed per weektimesNumber of weeksBricks\, removed = Number\, of\, bricks\, removed\, per\, week \\times Number\, of\, weeks

STEP 3

Plug in the given values for the number of bricks removed per week and the number of weeks to calculate the total number of bricks removed.
Bricks removed=3times5Bricks\, removed =3 \\times5

STEP 4

Calculate the total number of bricks removed.
Bricks removed=3times=15Bricks\, removed =3 \\times =15

STEP 5

The number of remaining bricks would be the initial number of bricks minus the total number of bricks removed.
b=Initial number of bricks−Bricks removedb = Initial\, number\, of\, bricks - Bricks\, removed

STEP 6

Plug in the values for the initial number of bricks and the number of bricks removed to calculate the number of remaining bricks.
b=40−15b =40 -15

STEP 7

Calculate the number of remaining bricks.
b=40−15=25b =40 -15 =25So, the equation that gives the number of remaining bricks in the pile after5 weeks is b=40−3(5)b=40-3(5).
