A. 1/4*2/2 = 2/8
B. 3/4*3/3 = 9/12 not10/12
C. 5/10*5/5 = 1/2
D. 10/12 divided by 2/2 = 5/6
D=-5
R=7 thats the answer to your question
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:
No, she will have 140 cards in 4 months
Step-by-step explanation:
the equations is:
f(x) = 100 + 10x
now x = 4
f(4) = 100 + 10(4)
f(4) = 100 + 40
f(4) = 140
140 does not = 60
Answer:
the average time spend is 0.111
Step-by-step explanation:
The computation of the average time spend is as follows;
Arrival rate is
= 210 ÷ 10
= 21 per hour
Now the service rate is
= 60 ÷ service time
= 60 ÷ 2 minutes
= 30 per minute
And, finally the average time spend is
= 1 ÷ (service rate - arrival rate)
= 1 ÷ (30 - 21)
= 0.111
Hence, the average time spend is 0.111
