Answer: 375
Step-by-step explanation:
Since we are given the information that there are 250 bricks used to build a wall 20 feet high, the number of brick used per feet will be:
= 250/20
= 12.5 bricks per feet.
Therefore, the number of bricks that will be used to buld a wall that is 30 fet high will be:
= 12.5 × 30
= 375 bricks.
Therefore, 375 bricks would be used.
10 oranges = $1
5 oranges = $?
To get from 10 to 5 you divide by 2 so that’s what you do with the $1 so it would be $0.50
You must do to the left hand side what you do to the right hand side.
We just want to get only A on the LHS and how much A is on the RHS.
A + 24 - 24 = -15 - 24 // we get rid of the +24 to only leave A and we do it on the other side because we always do that
A = -39
