Answer:
B, C, D
Step-by-step explanation:
4(4a + 5) = 16a + 20
Look at each answer individually.
A. 16a + 5 <u>This is not correct.</u>
B. 16a + 20 This is correct.
C. 12a + 20 + 4a = 16a + 20 This is correct.
D. 2(8a + 10) = 16a + 20 This is correct.
E. 16a + 5 + 4 = 16a + 9 <u>This is not correct.</u>
This is a system of equations. The first equation represents the tank being emptied and the second equation represents the tank being filled:
k = -10t + 528
k = 14t
To solve this system of equations, we will use substitution. The second equation says that k is equal to 14t, so we can substitute 14t for k in the first equation.
14t = -10t + 528
24t = 528
t = 22
Now that we have t, we can use it to find k by plugging it in to the second equation:
k = 14(22)
k = 308
So, it will take 22 minutes for both tanks to hold equal amounts of water. They will each hold 308 kiloliters.
Only one out of the possible answers does not contain at least one female lab technician.
Two of the careers that have more years of education are surgery and architecture.
Then, as per the positive correlation of the numbers of years of education and the amount of vacation time, you would expect that those carers have the most amount of vacation time.
