<h2>Answer:</h2>

The first consecutive odd number is: 9

and the second consecutive odd number is: 11

<h2>Step-by-step explanation:</h2>

Let the two consecutive odd numbers be: a and a+2

( Since, we know that the difference between two consecutive odd or two consecutive even numbers is always 2 )

Now, it is given that:

Three times the first is 5 more than twice the second.

i.e.

3a=5+2(a+2)\\\\i.e.\\\\3a=5+2a+4\\\\3a=5+4+2a\\\\3a=2a+9\\\\3a-2a=9\\\\a=9

Hence, we get:

The first consecutive odd number is: 9

and the  second consecutive odd number is: 9+2=11

<span>Totally, my expenses would be 60+200 = $260. Let us say that of this $100 would be met by the weekly bonus so that the residual part of the requirement is $160. </span>
<span>Let x be the number of hours I work. Then my earning would be 11x. For break even, earning should equal requirement. That is 11x = 160. And so, x = 160/11 = 14.55 hours/week </span>

alexandr402 [8]

Answer: Cruz's biking is 16 miles per hour and his running speed is 10 miles per hour.

Step-by-step explanation:

Let x represent Cruz's speed when running.

He left his house at 6:00 and ran until 7:30. This means that the time spent while running is 1hour 30 minutes = 1.5 hours.

Distance = speed × time

Distance covered while running would be

1.5 × x = 1.5x

Then he rode his bike until 9:45. This means that the time he spent riding his bike is 2hours 15 minutes = 2 hours + 15/60 = 2.25 hours

His speed when biking was 1.6 times his speed when running. It means his speed when biking would be

1.6 × x = 1.6x

Distance covered while riding would be

1.6x × 2.25 = 3.6x

He covered a total distance of 51 miles. Therefore,

1.5x + 3.6x = 51

5.1x = 51

x = 51/5.1 = 10 miles per hour.

His biking speed would be

1.6 × 10 = 16 miles per hour.
