8. Willow earns $10 per hour working part-time at a diner. Write and solve an inequality to determine
the number of hours, h, Willow must work in a week in order to earn more than $200. Then interpret
the solution.
Willow must work
hours this week.

Answers

Answer:

10h=200

h=20

10h=200

10h/10=200/10

h=20

Multiply the number of hours worked (h) by earnings per hour $10 to get

10h

This needs to be more than ( Greater than) 200

Now you have 10h > 200

Solve for h by dividing both sides by 10:

h >20

This means she needs to work more than 20 hours this week.

Answer:

66 degrees

Step-by-step explanation:

360 degrees in a circle

102 and 144 make up the circumference of LPN

LMN however is still to be determined... which is 360-(102+144) = 114

Therefore, LMN = 114 degrees. Using a thereom (I forget which one), the corresponding angle to LMN is LPN.

To find angle LPN (180-114) = 66

(x, y ) → (x + 10, y + 10 )

Step-by-step explanation:

Consider the coordinates of C and C'

C(- 7, - 1 ) and C'(3, 9 )

The translation in the x- direction is

- 7 → 3 = 3 - (- 7) = 3 + 7 = 10

The translation in the y- direction is

- 1 → 9 = 9 - (- 1) = 9 + 1 = 10

Then translation rule is

(x, y ) → (x + 10, y + 10 )

5 + 11y + 9 what is the answer
