You plug in number for number getting 194.8 which is equal to 2931
Answer:28
Step-by-step explanation:
Julio's number is x
(X-13)*-3=-45
Divide by -3
X-13=15
Add13 to both sides
x=28
Given that a certain antihistamine is often prescribed for allergies.
And typical dose for 100-pound person is 25 mg every 6 hours.
a) Let us calculate dose per 1 hour for 100-pound person= ![\frac{25}{6} mg/hr](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B6%7D%20mg%2Fhr)
Since 1 week means 7X24= 168 hours, dosage per 1 week = dosage per 168 hours
![=168X\frac{25}{6} = 700mg](https://tex.z-dn.net/?f=%3D168X%5Cfrac%7B25%7D%7B6%7D%20%3D%20700mg)
The number of 12.8 chew able tablets would be taken in a week= ![\frac{700}{12.8}=54.6875](https://tex.z-dn.net/?f=%5Cfrac%7B700%7D%7B12.8%7D%3D54.6875)
Hence number of 12.8mg chew able tablets would be taken in a week is 55.
b) Now we can use earlier answer for this problem, since 12.8mg tablet is replaced with 9ml liquid, 55 bottles of 9ml liquid are to be taken in a week.
Hence amount of liquid histamine should a 100-pound person take in a week = 55X9
=495ml
75d+8w+25
Part A)
75 and 8 are coefficients because coefficients are the numbers before and multiplied to the variable.
d and w are variables because variables aresymbols to represent the unknown numbers.
25 is the constant because constants are not affected by the variable.
Part B)
75d+8w+25
75(5)+8(48)+25 replace the variables
375+384+25 multiply
784 add
Part C)
No, because his stipend is a constant, and constants are not affected by the variable.
