Answer:
3x+(4x-1)+90°=180°{sum of angles in a triangle}
3x+4x-1+90°=180°
7x+89°=180°
7x=180°-89°
7x=91°
divide both sides by 7
x=13
Answer:
36
Step-by-step explanation:

The Solution:
Given:
Required:
To write the given equation in the form below:
Clearly, the given equation is already in the required form.
The parameters are:
Answer: 9 L
Step-by-step explanation:
Given
The dimension of the rectangular container is 
It is filled with 
of the height
Water present in the container
Also, 
Now, half of the water is poured out
So, half is left
Thus, 9 L of water is left in the container
Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>
<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>
<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>
<span>2c = 8 </span>
<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.
