Answer:

Step-by-step explanation:

Let m and n represent the numbers.  Then m + n = 97 and n - m = 7.

Solving the second equation for n, we get n = m + 7.  Substituting m + 7 for n in the first equation we obtain:

m + (m + 7) = 97, or

2m + 7 = 97, or 2m = 90

Dividing both sides by 2, we get m = 45.  Then n must be 52.

Which expression converts 8 radians to degrees? 8 times pi 8 times StartFraction pi Over 180 degrees EndFraction 8 times 180 deg
tensa zangetsu [6.8K]

Answer:

The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi

Step-by-step explanation:

To convert any number from radians to degrees we must use the equation below:

degrees = radians*180/pi

Therefore to convert 8 radians to degree we need to apply this value to the formula above:

degrees = 8*180/pi

degrees = 1440/pi

degrees = 458.366º

The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi
