Răspuns:
95.999
Explicație pas cu pas:
Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5
95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă
96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă
99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci
99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.
Folosind cunoștințele despre linia numerică:
95.999 <96.959 <99.595 <99.995
If the gum costs 75 cents today, which is 3 cents less than three times what the pack cost 20 years ago, we just need to arrange what we know into an equation.
We know that the price of gum today is 75 cents, so we can leave that on one side of the equation as a constant. Also, since we are dealing only with cents and not dollars, there is no need to shift the decimal point to the left.
? = 75
Now, we can work the equation.
The problem tells us that 75 is 3 cents less than three times the old cost. So, if x is the old cost, we can work out the equation based on that.
It says that it's 3 cents less than 3 times x. The question is basically the equation in word form.
3x - 3 = 75
'3x' being the "three times the old cost" part, '- 3' being the "3 cents less" part, and '75' of course being the current price of a pack of gum.
Option C is your correct answer.
BTW if we were to solve this, we would see that the old price of a pack of gum is:
3x - 3 = 75
+ 3 + 3
3x = 78
/3 /3
x = 26
20 years ago, a 75-cent pack of gum cost 26 cents.
Hope that helped! =)
It says The temperature doubled
It means the temperature has been doubled ,
if earlier it was t , then now its 2t
Now in the question it says the the temperature doubled
And now the temperature is 32 degrees ,
so we double it to get the new temperature
and the double of 32 degrees is 64 degrees
So
The value of the expression when t = 32 degrees is 64 degrees
