Answer:
The system of equations representing the situation are
with solutions
Step-by-step explanation:
Let us call 
the number of associates and 
the number of partners. If each associate costs $600 and each partner costs $1200, and it cost the law firm a total of $15,000, then we have
.
Since the law firm assigned at total of 16 lawyers, we have
.
Thus, the system of equations representing the situation are
And the solution to this system is found by solving for in the second equation and substituting its value in the first equation:
We put this value into and solve for 
Answer:
set middle number=x
then left side number=x-1
and right side number=x+1
(x-1)+x+(x+1)＝30
3x=30
x=10
x-1=9
x+1=11
numbers are 9,10,11
Answer:
7hours and 30 minutes
Step-by-step explanation:
given a car travels with a speed of 50 miles -------->1hour
x miles -------->6hours
on cross multiplying we get the value of 'x'
x = 50×6 = 300
x=300miles
Now ,
40mls------->1h
300mls------->xh
x= 300/40
x=(3/4)×10
x= 7.5hours
x= 7½hours
from the picture in every cup there are 1/5 of lemon + 4/5 of water.
the cups are 20
so 1/5 * 20 = 4
4 cup of lemon
