Answer:
35
Step-by-step explanation:
5x+6x+13 = 90
x=7
5x=a
5(7)=35
Answer:
If you want to know how many calories in 3/4 cup of honey, then just multiply 60 by 6, which is 360. So, there are in fact 360 calories in 3/4 cup of honey
Answer:
f ( x ) = -3x + 1
to find it's inverse let f(x)= y
y= -3x + 1
x = - 3y + 1
-3y = x -1
y = -(x -1)/3
Hope this helps.
Hello There!
Area = l x w
14 =
Multiples of 14:
1 and 14
7 and 2
7 and 2 are the only ones with a difference of 5.
Therefore, the length is 7ft and the width is 2ft.
Hope This Helps You!Good Luck :)

Answer:
274 mL
Step-by-step explanation:
Often medical solutions expressed as a percentage are not really a percentage as such. A percentage is the ratio of two quantities with the same units.
Here, the context given by the problem suggests the "25%" solution is really (25 g)/(100 mL). That is, the units are grams and milliliters--different units.
With that assumption, we want to find the volume (v) of solution needed to deliver 6 g of medicine. An appropriate proportion* is ...
v/(6 g) = (100 mL)/(25 g)
v = (6 g)(100 mL)/(25 g) = 24 mL
So, the total volume of the infusion is ...
250 mL +24 mL = 274 mL
_____
* The concentration is given in terms of g/mL, but we have used a proportion that is mL/g. The reason for that is we want the variable to be in the numerator of the ratio. The variable here represents volume, so we have written the proportion with volumes in the numerators.
Having the variable in the numerator means the equation can be solved in one step--by multiplying by its denominator.
