It is given that R=2q-5 and Q=3p+2. Find the numerical value of R when p=3

saveliy_v [14]

Answer:

R = 17

Step-by-step explanation:

R = 2q - 5

Q = 3p + 2

Find the numerical value of R when p = 3

R = 2q - 5

R = 2(3p + 2) - 5

R = 6p + 4 - 5

R = 6p - 1

When p = 3

R = 6(3) - 1

R = 18 - 1

R = 17

Find the difference. On February 6, 1995, in Sioux Falls, South Dakota, the temperature dropped from 48°F to –16°F in a period o

gtnhenbr [62]

Answer:

The average change in temperature per hour was -8°F.

Step-by-step explanation:

Using the equation 48-(-16) we know that the temperature dropped by 64°F.

$48-(-16)=64$

We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.

$\frac{-64}{8} = -8$

Therefore, the average change in temperature per hour was -8°F.
