Hi there! I believe the answer is 1080!
Step-by-step explanation:
First, find out how many bricks were stacked in one hour. The two hour rate was given, so just divide 1440 by 2. That gives you 720. So you have the one hour down. (It's easier to work with one hour.)
Next, you need to find out how many bricks are stacked in the 0.5 period of time. That, you get by just dividing 720 by 2.(because 720 is how many bricks were stacked in one hour) And that gets you 360!
Now, to find the full answer, (1.5 hour brick rate) just add the two numbers.
720+360= 1080
Hope this helps c:
Toodles~
Use PEMDAS
6X4=24 so you get rid of 6 and 4 and you get (24 - 4 + 9 -3)=26
16 as 1-4 =4secs so 1-16=16
Answer:
I do not think you can simplify it any further
Step-by-step explanation:
If you mean 15p squared - 7 q squared
Because they have different variables; p and q cannot be combined unless it is multiplication or division.
X=4 so your problem now would be 3+4=7
Hope this helps!
So in short your answer is 4
