Step-by-step explanation:
Answer:
7/8
Step-by-step explanation:
Because he has three brothers, and it also depends on how many times the spinner turns on each turn
time= distance/speed
take distance as d. take time as t.
the time taken: d/ 65 for the train however it is the same distance for d/130 so we can say (d/65)-3 = d/130
now solve the equation, multiply both sides by 130
2d-390=d
2d-d=390
so d=390 mi
<h2>
The required "option B) xy = 12" is correct.</h2>
Step-by-step explanation:
Check the options:
A) 4x = 12
Dividing both sides by 4, we get
⇒ x = 3
4x = 12 is a linear equation in one variable x.
B) xy = 12
xy = 12 is a non-linear equation.
D) 3x - 6y = 12
Dividing both sides by 3, we get
⇒ x - 2y = 4
3x - 6y = 12 is a linear equation in two variables x and y.
Thus, the required "option B) xy = 12" is correct.
