Answer:

His rate of change is 7 pounds per week.

Step-by-step explanation:

Rate of change = change in weight ÷ change in time

change in weight = 188 - 167 = 21 pounds

change in time = 6 - 3 = 3 weeks

Rate of change = 21 ÷ 3 = 7 pounds/week

Answer:

He loses 7 pounds per week

Step-by-step explanation:

After 3 weeks he weighs 188 pounds.

After 6 weeks he weighs 167 pounds.

Weight loss = (188 - 167) pounds = 21 pounds

Time interval = 6 weeks - 3 weeks = 3 weeks

Rate of change = Weight loss ÷ time interval = \frac{21}{3} pounds per week = 7 pounds loss per week.

You are a young entrepreneur who ventures into selling milk tea. On the soft opening day, you sold all 50 glasses of classic and
shutvik [7]

Answer:

35 glasses of classic milk tea

15 glasses of flavored milk tea

Step-by-step explanation:

You sold 50 glasses of classic and flavored milk tea.

c + f = 50

You made 4700 when classic tea costs 100 and flavored tea costs 80.

100c + 80f = 4700

Use this system of equation to solve.  Use substitution.  Rearrange the first equation so that it is equal to c.  Then, plug the c-value into the second equation.

c + f = 50

c = 50 - f

100c + 80f = 4700

100(50 - f) + 80f = 4700

5000 - 100f + 80f = 4700

5000 - 20f = 4700

-20f = -300

f = 15

Plug the f-value into one of the equations and solve for c.

c + f = 50

c + 15 = 50

c = 35

35 glasses of classic milk tea and 15 glasses of flavored milk tea were sold.

algol [13]

Answer:

24

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

So

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>

6, 12, 18, <u>24</u>

8, 16, <u>24</u>

They all share 24 so this is the LCM

Hope this helps
