Answer: The correct choice is that he can maximize his earnings by working 12 hours as a tutor and 3 hours as a lawn mower.
James will make the most money by working at the job that pays him the most. However, he has to work at least 3 hours at $10 per hour.
Therefore, he should work only 3 mowing lawns and the rest tutoring.
Step-by-step explanation:
let 1 pound of nail = x
so, the carved out waste nail will be = 12x
total nails = 13x
so the equation is =
13x - 12x = x
OR
x + 12x = 13x
Or
13x - x = 12x
Answer:
yes he can
Step-by-step explanation:
Using ASA congruency theorem:
angle ABD=CBD=ADB=CDB and BD concludes they are congruent triangles
The answer would be
X = 6 - y / 2 !
I am unfortunately not too sure about this, I have not heard of a proportional equation before even after getting my degree, because an equation usually isn't proportional, only expressions are and there are usually 2 terms.
Here's my best attempt. The first equation isn't proportional since y is inversely proportional to the 7 in the denominator. The second is proportional, and the k constant is 10.
I cannot provide any further explanations.
