Answer:
15/3 + (6.5 + 4.2) - 0.6 = 15.1
Step-by-step explanation:
You can first reduce the fraction to 5 when you multiply by 3, then calculate what's in the parenthesis. So now you have 5 + 10.7 - 0.6, then just solve from left to right. Hope this helps
Answer:
x= ?
Step-by-step explanation:
Step-by-step explanation:
the answer is 2/7 2578 (25510 - just positive
Answer:
- x > -2
- n ≤ -2 or n ≥ 8
Step-by-step explanation:
<h3>1.</h3>
Add 7x-2 to both sides and collect terms.
2x +2 -6x +7x -2 > -4 -7x +7x -2
3x > -6
x > -2 . . . . . . . divide by 3

<u>Answer</u>:
It takes 5 seconds for the sandbag to hit the ground
<u>Explanation</u>:
Given:
Height at which the sand bag is released from the hot air balloon
To find:
Time taken for the sandbag to hit the ground, t =?
Solution:
The initial height =s
Initially the height will be 0
Hence
the falling object model equation
Substituting the values we get,
Result:
Thus it takes 5 seconds for the sandbag to hit the ground
