Answer:
Yes. 30 divided by 10 is 3. Three times is right. Aaron is right
Step-by-step explanation:
Answer:
![0\leq x\leq42](https://tex.z-dn.net/?f=0%5Cleq%20x%5Cleq42)
Step-by-step explanation:
We have been given that checking account earnings at Long's Bank are expressed by the equation
. The earnings at Fellow's Bank are modeled by
. In both cases x is the number of checks written.
To find the number of checks that will generate more earnings at Long's bank then Fellow's Bank, we will set an inequality as:
Now let us solve for x.
![-0.06x+0.02x+8.3>-0.02x+0.02x+6.6](https://tex.z-dn.net/?f=-0.06x%2B0.02x%2B8.3%3E-0.02x%2B0.02x%2B6.6)
![-0.04x+8.3>6.6](https://tex.z-dn.net/?f=-0.04x%2B8.3%3E6.6)
![-0.04x+8.3-8.3>6.6-8.3](https://tex.z-dn.net/?f=-0.04x%2B8.3-8.3%3E6.6-8.3)
Now let us divide both sides of our inequality by -0.04. Since dividing by a negative number swaps sign of inequality, so our inequality will be:
![\frac{-0.04x}{-0.04}](https://tex.z-dn.net/?f=%5Cfrac%7B-0.04x%7D%7B-0.04%7D%3C%5Cfrac%7B-1.7%7D%7B-0.04%7D)
Since the number of checks needs to be integer, so number of checks will be:
![0\leq x\leq42](https://tex.z-dn.net/?f=0%5Cleq%20x%5Cleq42)
Therefore, the number of checks between 0 to 42 checks will generate more earnings income at Long's Bank than Fellow's Bank.
If P = b + a + c, and we are to solve for b, subtract a and subtract c from both sides:
P - a - c = b (answer)
Answer: isn’t it 1.6 because you multiply 5 x 5 x 5 = 125 and then you divide 200\125 =1.6
