13+14=180°
12x-22+9x-29=180
21x-51=180
x=11
m<2=m<14
m<2=70°
He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.
6 = r(1/2) divide each side by 1/2 (The time has to be in hours)
12 = r
So he was going 12 miles an hour.
The answer would be 0.375
Let r be the number of cards Ron has.
r + 2r + 4 = 97
3r + 4 = 97
3r + 4 - 4 = 97 - 4
3r = 93
3/3r = 93/3
r = 31
Ron has a total of 31 cards and Jason has a total of 66 cards.
The third option is the answer
