The tenth place is the first number to the right of a decimal. To determine if you're rounding or not, check the hundred's place, 2 numbers to the right of a decimal, for 5 or higher. If it's .45, round to .5, if it's .44, round to .4
Your answer is 524.5, which is B.)
I think what you would do is subtract the "salvage value" of 4,000 from 22,000 to get 18,000. Then since you need the number of years, you would divide 22,000 by the depreciation price of 3,600 to get 5. It would take 5 years for the car's value to reach 4000, therefore she would want to sell it before then.
Answer:
For the first one:
y = 2/3x + 1
For the second one:
y = -5x + 4
Step-by-step explanation:
As you may already know, in the y=mx+b equation format:
m = slope
b = y-intercept
On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.
And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.
Then, you can just leave the variables y and x alone.

Step-by-step explanation:
Hi there!
Let's solve this problem step by step!
A bottle contains 70% alcohol. First we need to convert this percentage into a decimal. To do this, we only need to divide by 100.
70 % = 70 / 100 = 0.7
The entire bottle contains 500 ml of solution. To find the amount of alcohol in the solution, we must multiply our (just found) decimal by the total content of the bottle.
0.7 * 500 ml = 350 ml
Therefore there are 350 millimetres of alcohol in the solution.
