I do not under stand need more info
We'll first need to find the area of one brick. We'll do this by doing length × width × height.
14 × 8 × 5
= 560
So one brick is 560in³.
Now, to find how many bricks there are, we'll divide the total area of concrete (16,800in³) by the area of one brick (560in³)
16,800 ÷ 560
=
30
There are 30 bricks that the company made.
Answer:
-20
Step-by-step explanation:
7m − 4 − 9m − 36 = 0
-2m - 4 - 36 = 0
-2m - 40 = 0
-2m = 40
m = -20
Answer:
12 and 52
Step-by-step explanation:
Let x and y be the 2 integers with x > y, then
x + y = 64 and
x = 3y + 16 ( 16 more than 3 times the smaller )
Substitute x = 3y + 16 into x + y = 64, that is
3y + 16 + y = 64
4y + 16 = 64 ( subtract 16 from both sides )
4y = 48 ( divide both sides by 4 )
y = 12 and x = 3(12) + 16 = 36 + 16 = 52
The 2 integers are 12 and 52
