Answer:
Sana takes 10 minutes longer than Ali in bathroom
Step-by-step explanation:
Given:
Ali Showers, brushes teeth 20 minutes
Thus, Ali takes 20 minutes time in bathroom
Sana Takes a bath, brushes teeth ½ hour
1 hour has 60 minutes
1/2 hour has 60/2=30 minutes
Thus, Sana takes 30 minutes time in bathroom.
Time, taken more by sana than Ali = 30 minutes - 20 minutes = 10 minutes
.
Thus, Sana takes 10 minutes longer than Ali in bathroom.
I’m not 100% but l’ll say go for D
Answer:
- 20 -5k = 4
- the LCM of the denominators is 10
Step-by-step explanation:
I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.
The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...
5(4 -k) = 4
Now, distributing, we get ...
20 -5k = 4
Answer:
Step-by-step explanation:
Here,

[put y =1,x=2]
⇒
k
=

Answer:
The graph is shown below.
Step-by-step explanation:
Given:
Slope of line =3
The line passes through the point (2,3)
To graph the line.
Solution:
In order to graph the line, we will first find the equation of the line.
Using point slope equation of line:
where 
represents slope of line and 
represents the point on the line.
Plugging in the slope and the point given in the equation.
Using distribution.
Adding 3 both sides.
Thus, we can graph the equation of the line.
When 
Point (0,-3)
We have two points (2,3) and (0,-3) to graph the line.
