Answer:
26km
Step-by-step explanation:
The train can travel 78km per hour or per 60 min
78 = 60
x = 20
Cross multiply:
(78)(20) = 60x
1560 = 60x
x = 26
Thus the train travels 26km in 20 min
Good morning,
Answer:
<h2>r = 4 cm</h2>
Step-by-step explanation:
V = h × (base area)
= 12 × (π×r²)
then 192π = 12π×r²
Then 192 = 12×r²
Then r² = 192÷12 = 16
Then r = √16 = 4.

Answer:
E
Step-by-step explanation:
subtract 317 from 609.
I want to say neither because it is only touching 2 sides.
Though its been a while
7x + 6 < 3(x - 2)
7x + 6 < 3x - 6
7x - 3x < -6 - 6
4x < -12
x < -12/4
x < -3
<span>{x | x < -3}</span>
