Answer:the volume formula is in the reference sheet.
Step-by-step explanation:
we name bases k , k+6. so
area: 96= (k + k+6).8/2
=> 2k+6= 24 => k=9
I'll use t for the messages Teresa sent, e for messages Eric sent, and r for messages Ryan sent.
Therefore we have, t+e+r=99.
From the text we also know:
e=3r ; r=t+6
If we substitute in the original equation we get:
t+3(t+6)+t+6=99; By simplifying it we get
5t=75 , therefore t=75/5=15.
Since Teresa send 15 messages,Ryan sent 6 more then here, so he send 21. Eric sent three times the
messages Ryan sent so he sent 63 messages. If we add them together 15+21+63, we get the total of 99 messages.
The answer to this one is simple.
An equation to model with would be
? * 4 = 56.
To find ? All you have to do is divide 56 by 4.
So the answer to your question is 14 miles per hour.
Hope I did this right and hope I helped you :))))
