Step-by-step explanation:
It says for you to multiply.
How can I send you the drawn representation on number line ?
25)
z + 4 >= 2z
-z >= -4
z <= 4 (you flip the sign when you divide over negative number)
on number line: from 4 to -infinity
you use normal arithmetic like equations
29)
-9 + 2a < 3a
-9 < a (just one step done)
on number line from -9 to infinity
41 and 43 ? not in the page
For this case we have the following data:
700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:
700 -----------> 500%
x ---------------> 100%
Where x represents the rabbit population of last year.
Clearing x we have:
rabbits
In this way, last year there was a population of 140 rabbits.
Answer:
140 rabbits
Answer:
2 Hours
Step-by-step explanation:
Required man hours to complete the full job = 12 *15
=180 Man hours
Required man hours to complete the 2/5 of the job = 180/5
= 36 Man hours
if 18 peoples are working,
required hours to complete the 2/5 of the job = 36 /18
= 2 hours
