Answer:
D: 6
Step-by-step explanation:
Let x mph be the rate of the faster jogger
Therefore (x-2) mph is the rate of the slower jogger
After 3 hours faster jogger will be 3x miles from the starting point
Whereas after the 3 hours slower jogger will be 3(x-2) miles from the starting point but in the opposite direction.
Since they are 30 miles apart 3x+3(x-2)=30
3x+3x-6=30
⇒ 3x+3x=30 +6
⇒ 6x=36
⇒ x=6
Therefore the rate of the faster jogger = 6 mph
Answer:
156
Step-by-step explanation:
1) The formula for finding the sum of interior angles of an n-gon is 180(n-2)
2) Plug in 15 for n
180(15-2)
3) Solve
180(15-2)
180(13)
2340
4) There are 15 angles in a 15-gon
5) Divide sum of interior angles by number of interior angles
2340/15 = 156
6) So, the answer is 156 degrees
This is the equation: ×+2x+5x+1=25 Combine
like terms to get:
8x+1=25 Now subtract 1 from both sides to
result in;
8x=24 Divide 8 into both sides to get:
×=3 inches for the first one.
