Hi there!

To find the unknown addend, we can just subtract:

1 - 2/6 = 4/6
4/6 = 2/3

Hope this helps!

2/6 + 2/3 = 1

To find this, you would replace the blank with a variable (x), and calculate.

2/6 simplified is 1/3

1 - 1/3 = 2/3

Hope this helped. ♡

Damm [24]

Answer: Elaine=13 years old Tyler=21 years old

Step-by-step explanation:

Let x = Elaine's age, so her brother Tyler's age = x+8

 Elaine+Tyler=34

          x+(x+8)=34

             2x+8=34

                 2x=26

                   x=13

Elaine=13 years old

Tyler=21 years old

a freight train must approach a road crossing at 16 km/h. After passing through the intersection, the train speeds up rto 65km/h
grin007 [14]

v₀ = initial velocity of the freight train while it approach a road crossing = 16 km/h = 16 (5/18) m/s = 4.44 m/s

v = final velocity of the freight train after it crosses a road crossing = 65 km/h = 65 x 5/18 m/s = 18.06 m/s

t = time to do so = 10 min = 10 x 60 sec = 600 sec

acceleration is given as

a = (v - v₀ )/t

a = (18.06 - 4.44)/(600)

a = 0.023 m/s²

a = 294
