Answer:
He walks 150 km in 2.5 hours.
Step-by-step explanation:
From 9:30 a.m. to noon, it's 2.5 hours.
distance = speed * time
distance = 60 km/h * 2.5 h
distance = 150 km
Answer: He walks 150 km in 2.5 hours.
Answer:
0.3[x-2y] + 0.5x - y
Use the distributive property: a(b-c) = ab - ac
0.3x - 0.6y + 0.5x - y
Now, add/subtract all like terms
0.3x + 0.5x - 0.6y - y
0.8x - 1.6y
If you want, we can simplify that down further to:
0.8(x - 2y)
The standard form of any linear equation with two variables is

, where a, b, and c are constants. To convert this equation to standard form, simply subtract

from both sides to get

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get
Geometry
This makes a cube because a cube has 6 faces, 8 vertices, and 12 edges.
