Answer:
6/10 or 3/5
Step-by-step explanation:
4/5 = 8/10
8/10 - 2/10 = 6/10 or 3/5
The answer is .75 because this is a proportion problem so cm over miles is 1 over 2 equals x over 1.5 you cross multiply and get 2x=1.5 and divide both sides by 2 and you get x=.75
Distributive property
5 + 6x - 8 - x
Combine like terms
5 - 8 = -3
6x - x = 5x
Answer: -3 + 5x
Answer:
The lines intersect once at (2, −1).
A graphic solution to a system of equations is only as accurate as the scale of the paper or precision of the lines. At times the point of intersection will need to be estimated on the graph. When an exact solution is necessary, the system should be solved algebraically, either by substitution or by elimination.

Using proportions, it is found that:
2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.
3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For each of Alan and Bree, we have to find the proportions of words typed per second and mistakes per second.
Then, for Alan:
- Words typed per second: 5/6 = 0.83.
- Mistakes per second: 2/6 = 0.33.
For Bree:
- Words typed per second: 9/8 = 1.13.
- Mistakes per second: 3/8 = 0.375.
Then:
2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.
3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.
