Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?​
liraira [26]
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.

Answer: 78°

Step-by-step explanation:

Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.

4x+2+3x+3=180            [combine like terms]

7x+5=180                       [subtract both sides by 5]

7x=175                           [divide both sides by 7]

x=25

Now that we know x=25, we can plug it in to find ∠DCB.

3(25)+3                         [multiply]

75+3                               [add]

78

Now, we know ∠DCB is 78°.
