2x-5x(-7)=27
x=-4
5: six twelfths is one half
6: eight tenths is four fifths
7: four eighths is one half
8: ten tenths is two halves
9: two sixths is one third
10: one quarter, because you divide the top and bottom number by 3
method:
take the first one - four eighths, which is 4/8
the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)
49^2 or 7 I just know from 6th grade
the question in English
Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.
Let
x-------> the number of days
y------> the total liters of water
we know that
------> algebraic expression to determine the total liters of water that a person should drink a given number of days
For x=30 days (1 month)
substitute in the formula
therefore
<u>the answer is</u>
Answer:
2
Step-by-step explanation:
if you divided each number by the minute time you would then divide both numbers like 2 x 60 + 60 and 5 x 60+60+60+60+60=300 divided that with the two numbers and then you get 2
