Answer:
The formula for volume is l x w x h.
Step-by-step explanation
To find the missing link, we do the equation backwards.
l x 2.5 x 5 = 75
If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.
To check, do 5 x 2.5 x 6 which should equal 75
6 is your length
Answer: +19
Step-by-step explanation: In this problem we are asked to evaluate 9 - (-12).
To subtract these integers, it's important to understand that when we have minus a negative, we can change it to plus a positive.
So 9 - (-12) can be changed to 9 + (+12) or 9 + 12 which gives us a sum of 21.
Therefore, 9 - (-12) = +21.
Notice that I put the '+' sign in front of the 21. Although this is optional, it's a good idea to do especially when adding and subtracting positives and negatives. All it shows is that our answer is positive.
The correct answer is A.
That is because the whole paragraph talks about a model car that they are testing but this student is wondering about roller coasters.
Hope this helps :)
