Answer:

29 is the answer.

Step-by-step explanation:

90 + (x + 5) + (2x - 2) = 180

=> 90 + x + 5 + 2x - 2 = 180

=> 93 + x + 2x = 180

=> 3x = 180 - 93

=> 3x = 87

=> 29

Therefore, 29 is the answer.

Step-by-step explanation:

90 + (x + 5) + (2x - 2) = 180
x + 5 + 2x - 2 = 180 - 90
3x + 3 = 90
3x = 87
x = 29

Louisa ran at an average speed of five miles per hour along an entire circular park path. Calvin ran along the same path in the

docker41 [41]

Answer:

15 miles

Step-by-step explanation:

Let $x$ be the miles in the circular park path, $t_{L}$ the time Louisa takes to finish and $t_{C}$ the time Calvin takes to finish both in hours.

Then $x$ , the longitude is equal to the velocity times the time used to finish. So

$x=5t_{L}$

$x=6t_{C}$

And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:

$t_{C}=t_{L}-0.5$

Three equations, three unknowns, the system can be solved.

Equalizing the equation with x :

$5t_{L}=6t_{C}$

In this last equation replace $t_{C}$ with the other equation and solve:

$5t_{L}=6(t_{L}-0.5)\\ 5t_{L}=6t_{L}-3\\ 3=6t_{L}-5t_{L}\\ 3=t_{L}\\ t_{L}=3$

With Louisa's time find x:

$x=5t_{L}\\ x=5(3)\\ x=15$
