Answer: lesser x = 3.76 & greater x = 8.24
Step-by-step explanation: just took the test
add the like terms
14x=-3+x
subtract x from both sides
13x=-3
divide both sides by 13
x=-3/13
Given:


To find:
The value of
.
Solution:
We have,
![[\because d(t)=80t]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%28t%29%3D80t%5D)

Now,
![[\because C(d)=0.09d]](https://tex.z-dn.net/?f=%5B%5Cbecause%20C%28d%29%3D0.09d%5D)

Therefore, the value of
is 72.
Answer:
She increased 80% the practise time
Step-by-step explanation:
The question is incomplete, the following is missing:
<em>by how much did she increase the time she practised each day?
</em>
From Monday to Wednesday she increased 90 - 50 = 40 minutes the practise time.
To compute the increment as a percentage use: increment/reference *100
In this case, that is: 40/50*100 = 80%, where 50 minutes is taken as a reference.
<h2>Hello!</h2>
The answer is:
The coordinates of the midpoint are:

<h2>
Why?</h2>
We can find the midpoint of the segment with the given endpoints using the following formula.
The midpoint of a segment is given by:

We are given the points:

and

Where,

So, calculating the midpoint, we have:



Hence, we have that the coordinates of the midpoint are:

Have a nice day!
