Answer:
- 5m + 8
Step-by-step explanation:
Given:
(2m + 3) - (7m - 5)
If you want to find the differences between two values, it means you are to subtract
(2m + 3) - (7m - 5)
This means subtract (7m - 5) from
(2m + 3)
Step 1: Open parenthesis
(2m + 3) - (7m - 5)
= 2m + 3 - 7m + 5
Group like terms
= 2m - 7m + 3 + 5
= - 5m + 8
Or
= 8 - 5m
Precision is more like consistency. Take a rifle range for example. Sure, all the shots may be off centered, but if they're tightly grouped together, it shows that the shooter had precision in their shooting. Accuracy is how close to spot on the attempts or shots generally are. They would end up more towards the center, but a little more spread out.
Answer:
y = -3/4x -2
Step-by-step explanation:
Slope intercept is y = mx+b where m is the slope and b is the y intercept
4y = -3x-8
Divide each side by 4
4y/4 = -3x/4 -8/4
y = -3/4x -2
First you have to figure out the length of the track:
r is the half of the diameter:
200ft : 2 = 100ft
= 200
≈
628,31
The athlete has to run ca. 5280ft for one mile:
5280 : 628,31≈8,4
The athlete has to run 8,4 laps
