Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20
Answer:
3325/5=665
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
3x-9=12
add 9 to both sides
3x=21
divide both sides by 3
x=7
Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.
