Hi!
Let's plug in some values:
x = 0, 1, 2
y = 7(0) - 5
y = -5
y = 7(1) - 5
y = 2
y = 7(2) - 5
y = 9
So three solutions include (0, -5), (1, 2), and (2, 9).
Answer:
There are 0.70km in 765 yards.
Step-by-step explanation:
This is a problem of conversion of units, that can be solved by multiple rule of three's.
The first step is converting 765 yards to feet. We have that each yard has 3 feet, so
1 yard- 3 feet
765 yards - x feet
x = 765*3
x = 2295
So, in 765 yards there are 2295 feet.
Now, we have to convert 2295 feet to miles. Each mile has 5280 feet, so:
1 miles - 5280 feet
x miles - 2295 feet
5280x = 2295
x = 0.435 miles
So, in 765 yards there are 2295 feet which is 0.435 miles
Now, the final step is converting from miles to kilometers. Each km has 0.621 miles, so:
1km - 0.621 miles
xkm - 0.435 miles
0.621x = 0.435
x = 0.70km
So, there are 0.70km in 765 yards.
