Say 36% of 100 is 36. so knowing half of 36 is 18, take half of 100, 50.
so 18/50 = 36
The answer is 50.
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
We know, Volume of a Cube = Edge³
so, it would be: f(v) = a³
Hope this helps!
Answer:
210
Step-by-step explanation:
27 cards = 9$ = 27/9 = .4 cents per card
$84 divided by .4 = 210
its 4 cents a card because it cant be 3 dollars per card because if it was 3 dollars per card he would only have 3 cards.
