20 - 2x = 0
So, after 2 days, she has completed 4 hours and 20 - 4 = 16. That's the number of hours left.
the answer is, 7/11 a^3 b^4
Answer:
Step-by-step explanation:
To answer this question, a proportion is best. We know that 1 inches = 2 feet. So we want to find the feet measurement for 5 inches. When we set up a proportion, we get 1 inches/2 feet = 5 inches/ x feet. Now, you cross multiply, so you multiply 1 and X, and 2 and 5. As a result you get 1x=10. To get rid of the 1 in front of the X, you divide by 1 on both sides. As a result, you get that x=10 meaning that 5 inches is equal to 10 feet.

Mark me as brainliest...
False the origin has coordinates (0,0) so x=0 and y=0 if you sub these into the equation you get 0 < 0-5 which isn't true
