Increase=higher-lower=386-313=73
percent increase=increase/original times 100=73/313 times 100=0.23322683706070287539936102236422 times 100=23.322683706070287539936102236422
so it is about 23% increase
the increase is 73
A comparison of two numbers or variables is a proportion
Answer:
8 days
Step-by-step explanation:
To find how long they will last, take the number of pills, and divide by the number of pills a day
160/20 = 8
The pills will last 8 days, not even a month
M = - 10 + 9 / 2 + 5
m = - 1 / 3
Answer: Rewrite equations:
5x+y=−13;6x+6y=−6
Step: Solve5x+y=−13for y:
5x+y=−13
5x+y+−5x=−13+−5x(Add -5x to both sides)
y=−5x−13
Step: Substitute−5x−13foryin6x+6y=−6:
6x+6y=−6
6x+6(−5x−13)=−6
−24x−78=−6(Simplify both sides of the equation)
−24x−78+78=−6+78(Add 78 to both sides)
−24x=72
−24x
−24
=
72
−24
(Divide both sides by -24)
x=−3
Step: Substitute−3forxiny=−5x−13:
y=−5x−13
y=(−5)(−3)−13
y=2(Simplify both sides of the equation)
Answer:
x=−3 and y=2
