Every number has three cube roots.
The only real cube root of -64 is <em>-4</em> .
The other two cube roots of -64 are a pair of complex conjugates.
I'm too lazy to calculate them right now, and you didn't ask for them
anyway.
The average price is calculated by dividing the sum of all prices with the number of items.
average price= price1+price2+...priceN/N
In our case , we have four pairs of shoes.So, N=4.
We also know the average price. average price=$50
We also know the price of the first pair of shoes (price1), of the second (price2) and the third (price3). We need to find out Price4:
$50=$35+$40+$55+Price4/4
50*4=<span>$35+$40+$55+Price4
$200=$130+Price4
Price4=200-130
Price4=$70</span>
The answer to your question is A
Step-by-step explanation:
x+8=10
x−4=22
x÷3=6
7x=28
60=30+30=6+6+6+6+6+6+6+6+6+6
a=a
a=b,thenb=a
60=30+30,then30+30=60
ifa=bandb=c,thena=c
60=30+30
30+30=6+6+6+6+6+6+6+6+6+6
60=6+6+6+6+6+6+6+6+6+6
