Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3. He rewrote the expression as 16 + (–9) + (–12) +
malfutka [58]

Jaun has to use inverse before using those properties as they does not support subtraction but only addition.

<u>Solution:</u>

Given that , Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3.  

He rewrote the expression as 16 + (–9) + (–12) + 22

Juan can use the associative and commutative properties to rewrite the expression again.  

We have to explain why he had to use the additive inverse before he could use these properties.

Now, Associative property and commutative property true for addition.

i) a + (b + c) = (a + b) + c  ---> Associative property of addition

ii) a + b = b + a --> commutative property of addition.

These properties not true for subtraction.

That's the reason Juan used additive inverse before applying these property.

Hence, jaun has to use inverse before using those properties as they does not support subtraction but only addition.

Order 2.000 D5W IV to infuse over 12 hoursThe drop factor is 15 gtt/. Calculate the rate in gtt / min
PilotLPTM [1.2K]

Answer:

42gtt/m

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)

Where, Total fluid in ml = 2,000ml

Drop factor = 15gtt/m

Total hours = 12hours

By putting the following value in the formula, we get

Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)

= 30,000 ÷ 720

= 41.67 or 42gtt/m
