The question is incomplete. Here is the complete question:
Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.
Answer:

Denise has to work at least 67 hours in order to buy a computer that costs $2000.
Step-by-step explanation:
Given:
Hourly earning of Denise is $30.
Let the number of hours Denise works be 'h'.
Now, total earning of Denise can be calculated using the unitary method and is given as:

Now, total money earned by Denise must be at least $2000 in order to purchase a computer. Therefore, the inequality is given as:

Therefore, Denise has to work at least 67 hours in order to buy a computer that costs $2000.
Answer: 240
Step-by-step explanation:
You would multiply each of the sides to get the final answer of 240 (:
This will solved using the concept of proportionality:
(height of the cliff)/(height of the pole)=(base of the cliff)/(length from base of pole to the rope)
thus, let the height of the cliff be x, plugging the values in the formula we obtain:
x/6=86/7
hence solving for x we get
x=(86×6)/7
x=73.71 ft
Answer:
238 mm
Step-by-step explanation:
11x5 = 55
11x4=44
11x5=55
11x4=44
4x5=20
4x5=20
______(Add all up)
= 238 mm
Hope this helps :)
