Answer:

21

Step-by-step explanation:

The sum of degrees in a triangle is 180, so we have:

3x+100+x-4=180

add 4 on both sides

3x+100+x=184

subtract 100 on both sides

3x+x=84

Combine like terms

4x=84

84/4 = 21

Answer:

x=21

Step-by-step explanation:

x-4+100+3x=180

(180 are the degrees of a triangle added together)

subtract 100 on both sides

x-4+3x=80

simplify like terms

4x-4=80

add 4 to both sides

4x=84

divide 4

x=21

−5y+3x=3<br> −8y+9x=−12<br> ​<br> What is X and Y please.
Tomtit [17]

Answer:

( -4, -3 )

Step-by-step explanation:

Let's solve by elimination. Reason being there are no variables without coefficients.

−5y+3x=3     Multiply equation by 3. Each term.  

−8y+9x=−12

-15y + 9x = 9       Subtract the to equations

-8y  + 9x = -12

___________

-7y = 21

y = -3

Substitute y into original equation

-5(-3) + 3x = 3

15 + 3x = 3            Subtract 15 both sides

3x = -12                 Divide by 3, both sides

x = -4

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
