7x7x7x7 written in exponential form would be 7^4 or 7 to the fourth power.
hope this helps .
3(r-6)+2=4(r+2)-21
3r-18+2=4r+8-21
3r-16=4r-13
-3=r
r=-3
97 is the answer to your question
Area=Pi r squared
Pi*12*12
452.39cubic cm
To the nearest tenth =452.4cubic cm
It will be $2.50 for each pound of walnuts, and it will be $1 for each pound of chocolate chips.
I know this hold true because when we multiply $2.50 by 2, we get $5, and add that to the other $5 from the chocolate chips and we will get $10. We can also multiply $2.50 by 8 and add $3 from chocolate chips to get $20 + $3, or $23.
