Rules for rounding: If a number is less than 5, round down. If it is 5 or bigger, round up. Tenths is the one just to the right of the decimal. Since the hundredths is 5, we round up. The answer is 15.3

Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.

His displacement ... the distance between his start point and
his end point ... was 10 miles. But we don't know what route
he followed on the way, so we don't know how much distance
he actually walked or drove. It couldn't be less than 10 miles,
but it could be any distance more than 10 miles.
Is it F = 1/2 Don't take my word for it, though, I am just trying to solve it in a way that would give you an answer because the problem itself, didn't make much sense. Good Luck!
Answer:
49 people
Step-by-step explanation:
The inequality shows that she can only invite less than 50 people, and you can not invite a fraction or decimal , so the maximum is 49.
