4 is correct. Set up a ratio relationship between similar triangles.
Benchmark are numbers that are used as standards to which the rest of the data is compared to. When counting numbers using a number line, the benchmark numbers are the intervals written on the axis. For benchmark numbers of 10, the number line on top of the attached picture is shown. Starting from 170, the tick marks are added by 10, such that the next numbers are 180, 190, 200, and so on and so forth. When you want to find 410, just find the benchmark number 410.
The same applies to benchmark numbers in intervals of 100. If you want to find 170, used the benchmark numbers 100 and 200. Then, you estimate at which point represents 170. For 410, you base on the benchmark numbers 400 and 500.

Answer:
X = 100
Step-by-step explanation:
- In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
- This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
- Multiply the left by k, so
- we know that y= 5, for x = 36, so sub this in the equation
- simplify
- re-arrange for k, <u>k = 5*6 = 30</u>
- now we know k, we can create the real equation,
- sub in 3 as y
- <u>x = 100</u>
