Answer:
3 decimal points
Step-by-step explanation:
The trick here is to count the zeros.
Answer:
2x - xy = 0
Step-by-step explanation:
We need to solve the equations simultaneously to find the values of x and y:
x + y = 12
x - y = 8 - we need to add the equations together
2x = 20
x = 10
Then we substitute x into one of the equations to find y:
10 + y = 12
12 - 10 = y
y = 2
Now we substitute x and y into the final expression:
2(10) - 2(10)
20 - 20 = 0
Answer:
The coefficient is 6
Step-by-step explanation:
Answer:
2 km 691 m
Step-by-step explanation:
5 km - 2 km 309 m
= 5000 m - 2309 m
= 2691 m
= 2 km 691 m
the first part isn't 90, it's 180.
the whole circle is 360, half of 360 is 180
an acute angle is any angle less than 90 degrees.
