Mathematics

Evgen [1.6K]4 years ago

Distribute

(2/5) (a) + (2/5) (b) + (3/5)(a) +(3/5)(c)

= 2/5a+2/5b+3/5a+3/5c

Combine like terms

2/5 a + 2/5 b + 3/5 a + 3/5 c

= ( 2/5 a + 3/5 a ) + ( 2/5 b) +(3/5 c)

= a + 2/5 b +3/5 c


I hope that's help !

A raindrop falls at 200m per minute. how long will it take a raindrop to travel 6000m?
Kryger [21]
The first thing you should know is that by definition:
 d = v * t
 Where
 d: distance
 v: speed
 t: time
 We then have to clear the time:
 t = (d) / (v)
 Substituting the values:
 t = (6000) / (200)
 t = 30 minutes
 Answer: 
 It will take a raindrop to travel 6000m about: 
 t = 30 minutes

Anastaziya [24]

Answer:

<CAB and <DAE are vertical angles

<EAB and <CAD are vertical angles

Step-by-step explanation:

this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.
