We're down 125*5 (for 5 days), so we subtract that to start it off. Next, he gets 12 dollars per every wind chime, and we can write every wind chime sold as x to get -625+12x. Next, we need that to equal 3500, so we get -625+12x=3500. Adding 650 to both sides, we get 4125=12x. After that, we divide both sides by 12 to get 4125/12=x
Answer:
8.652
Step-by-step explanation:
Ignore the points and multiply, then you see that 4.12 has two decimal places and that 2.1 has one decimal place, when you add them there is three decimal places.
412 x 21 = 8652
4.12 x 2.1 = 8.652
Pls mark me as brainliest!!!!
Therefore, the function is not differentiable at x = 1.
Therefore, the function is not differentiable at x = 0.
Answer:
210 ÷7 = 30
Step-by-step explanation:
We can round the numbers to numbers that make the math easier
I will round 208 to 210
We know 21 divide by 7 is 3
210 ÷7 = 30
This is very close to the actual answer.
208÷7 = 29.71428571........
