Answer:
2x-5y-20=0
Step-by-step explanation:
2y=-8+4/5x
2y+8-4/5x=0
10y+40-4x=0
5y+20-2x=0
-2x+5y+20=0
2x-5y-20=0
B and d because you can rotate it to make the same shape
Answer:
40,000 workers
Step-by-step explanation:
This question deals with simple rates proportion.
If it takes 20 years for X workers to complete a job,
if we double the amount of workers, we will take half the time.
hence to halve the time from 20 years to 10 years, we will need to double the amount of workers.
In this case we will need 20,000 workers x 2 = 40,000 workers
Answer:
Step-by-step explanation:
The given expression is
We group the constant terms on the right hand side to obtain;
We square both sides of the equation to remove the square root.
This will simplify to;
Decimal=9.03 &
fraction= 9 3/100
