Kaylee is working till summer jobs making six dollars per hour walking dogs and $13 per hour landscaping. Last week kaylee worked a total of eight hours and earned a total of $83. Determine the number of hours kaily worked walking dogs last week in the number of hours she worked landscaping last week

the number of hours that Kaylee worked walking dogs last week is 3 hours.

the number of hours that Kaylee worked landscaping last week is 5 hours.

Step-by-step explanation:

Let x represent the number of hours that Kaylee worked walking dogs last week.

Let y represent the number of hours that Kaylee worked landscaping last week.

Kaylee is working two summer jobs making six dollars per hour walking dogs and $13 per hour landscaping.

Last week, she earned a total of $83. It means that

6x + 13y = 83- - - - - - - - - - - -1

Last week kaylee worked a total of eight hours. It means that

x + y = 8

Substituting x = 8 - y into equation 1, it becomes

6(8 - y) + 13y = 83

48 - 6y + 13y = 83

- 6y + 13y = 83 - 48

7y = 35

y = 35/7

y = 5

x = 8 - y = 8 - 5

x = 3

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
