The solution to the given expression [98/(82 + 283)] * (69 - 29) is; 784/73
<h3>How to solve simple arithmetic operations?</h3>
We want to solve the expression;
[98/(82 + 283)] * (69 - 29)
Let us first simplify the first part which is;
98/(82 + 283) = 98/365
Then let us simplify the second part which is;
69 - 29 = 40
Thus, we have the expression;
(98/365) * 40
This can be simplified further to get;
(98/73) * 8 = 784/73

To convert km/s to m/min, multiply by 1000*60=60000
hence 0.85km/s=51000 m/min
The first one is the correct answer, just finished it
Answer:
100
Step-by-step explanation:
The original area is (200 m)×(300 m) = 60000 m². You want an area that is ...
(200 +x)×(300 +x) = 120000
60000 +500x +x² = 120000 . . . . eliminate parentheses
x² +500x -60000 = 0 . . . . . . . . . . subtract 120000
(x +600)(x -100) = 0 . . . . . . . . . . . . factor
The positive value of x that makes a factor zero is x = 100.
The value of x is 100.
