Answer:
The greater than or equal to sign is:
>= or ≥.
Now let's solve for this <u>inequality</u>.
-8x + 5 ≥ -3
First, we need to get rid of any <u>constants</u>.
Get rid of a constant by performing the inverse operation of it, we always apply this to both sides of an inequality.
The inverse operation of addition (since it is a <u>positive</u> 5) is subtractions.
So, we subtract 5 from both sides;
-5 -5
Now we have:
-8x ≥ -8
Now, all we need to do is isolate x from it's co-efficient, 8.
To do that, we also utilize the inverse operation.
The inverse operation of multiplication (since -8 is being multiplied by x) is division, we apply this to both sides of this inequality.
So, we divide by -8 from both sides;
÷ -8 ÷ -8
And we'll end up with:
<u>x ≥ 1</u>, therefore the solution to this inequality is <u>1</u>.

Step-by-step explanation:
The answer is that 80 people will build the same road in 160 days.
Given that 50 people take 256 days to build a road.
And we need to find out how many days will 80 people take to build the same road.
Disclaimer: Assuming that the work done by all the people are same.
If the number of people increases, the time taken to build the road decreases in the same proportion. Clearly, the number of people varies inversely to the number of days.
Let x denote the number of days required to build the road for 80 people.
Then the ratio, 80/50 = 256/x
⇒ x = (256×50)/80 = 160
Therefore, 80 people will build the same road in 160 days.
