I'm not exactly sure how to approach this problem because it does not have an output, but we can combine like terms.
Add all the x, y, and z together with the numbers.
3x-3y+7z is the final answer.
4)C
5)A
6)D
7)-4/3x-1(use formula y=mx+b, m is slope, x and y is the x and y of the one point that is given, b is y-intercept)
8)B
***Slope is the number multiplied with the x and y-intercept is the last number. It's obvious
There are 1,61 kilometers in a mile or more correctly 1,60934 kilometers in a mile.
<span>But first, a short history.... Both kilometers and miles are units of measurement. They are used to measure distance. Miles are part of the imperial measurement system and kilometers are part of the metric measurement system. </span>
To calculate how many miles a person will run during a 10-kilometer race, you need to divide 10 kilometers by 1,61 miles (1,60934 rounded up to two digits).
Therefore your equation is as follows:
10÷1,61 or 10 000 meters ÷ 1 610 metres
1000 meters is equal to 1 kilometer.
The answer = 6, 21 miles.
Therefore, a person who runs 10 kilometers will run 6,21 miles

25 min = 0.4166 hours
7.5 hours / 0.4166 = 18
