Answer:
This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8). The previously unknown x-coordinate is 16.
Step-by-step explanation:
A line with slope m = -1/5 passes through the points (x, 7) and (11, 8). Find the value of x.
The slope of the line through these two points is found from the slope formula and is:
8 - 7
m = ----------- and the value of m is given as -1/5. Therefore,
11 - x
1
m = ----------- = -1/5
11 - x
Cross-multiplying, we get (1)(5) = -(11 - x), or 5 = -11 + x. Then x = 16
This tells us that the line with slope -1/5 passes through the two points (16, 7) and (11, 8). The previously unknown x-coordinate is 16.

Answer:
2:5
Step-by-step explanation:
The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.
1. 800g is already in grams, so leave it.
2. 2kg is in kilograms, and 1 kilogram = 1000 grams.
3. 2 kilograms is equal to 2000 grams.
4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.
<u>That is the ratio, 2:5</u>
