Answer:
33x-25
Step-by-step explanation:
2(3x-5)-3(6-4x)+(15x+3)
6x-10-18+12x+15x+3
21x+12x-10-18+3
=33x-25
Answer is 3.75%
3.75% = 0.0375
0.0375 + $2,100 = <span>$78.75</span>
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
<h3>
Answer:</h3>
It would be 21b² -32b -5
<h3>
Step-by-step explanation:</h3>
By using the FOIL method, you can simplify the equation.
<em>The Foil Method is </em><u><em>ac + ad + bc +bd</em></u><em>, or </em><u><em>First, Outer, Inner, Last.</em></u>
First, you multiply the first term in each bracket.
3b * 7b = 21b²
Next, you multiply the outer term in each bracket.
3b * 1 = 3b
Then, you multiply the inner term in each bracket.
-5 * 7b = -35b
After that, you multiply the last term in each bracket.
-5 * 1 = -5
Lastly, you combine like terms.
21b² + 3b -35b -5 ---> 21b² -32b -5
<em>21b² -32b -5 would be your answer, since you cannot simplify the equation anymore.</em>
Answer:
13
Step-by-step explanation:
write a proportion: 25 : 100
13 - x into percent.
13 = 25
100 = x
cross multiply and you have your answer.
