1) Distribute
2x + 28x + 21
2) Combine like terms
30x + 21
Since there are no more like terms, 30x and 21 cannot be combined. Therefore, the answer is 30x+ 21
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Average number of arrivals = 6 per hour
Service rate = 3 every 15 minutes
Service rate is given by

So, the average number of customers in the system is given by

Hence, Option 'c' is correct.
Answer:
Step-by-step explanation:
A, B & C lie on a straight line.
D, C & E lie on a different straight line.
Ah, this is 2 intersecting lines
angles
y
= 106° and angle
z
= 64°.
well we know that a full size of circle is 360 degrees
let's add z and y :
106+64 = 170
then, let's subtract it from 360
360 - 170 = 90
we must devide it by 2, why? because 90 is from two section of x (2x)
so 90/2 = 45
and there you have it x = 45
if you still cannot visualize what is intersecting line mean, then see the file below
Answer:
5x+8
Step-by-step explanation:
We have to distribute the + into -7x+5. So the equation will now be 12x+3-7x+5. Now let's organize it into terms. 12x-7x+3+5. Now let's simplify this. The final answer is 5x+8. That is the final answer!
Hope this helped!!! :D
