Answer:
CS = 4
Step-by-step explanation:
From the figure below;
Triangle ABC is similar to triangle RSC
Therefore, the ratio of the corresponding sides in the two triangles is equal;
That is;

In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS
But; 
AC=CR + RA
= 5
Assuming CS is y, then


Therefore, CS is 4
Underscore is that line lowered
Answer:
Step-by-step explanation:
Let the required amount is x.
<u>Alcohol content is same at the end:</u>
- x*0.17 + 4*0.2 = (x + 4)*0.19
- 0.17x + 0.8 = 0.19x + 0.72
- 0.19x - 0.17x = 0.8 - 0.72
- 0.02x = 0.08
- x = 0.08/0.02
- x = 4
The slope of the line that passes through the points, (3, 4) and (-4, -5) is: A. 9/7.
<h3>How to Determine the Slope of a Line?</h3>
The slope of a line can be calculated by using the slope formula, which is given as:
Slope (m) = change in y / change in x or rise / run.
Given that the following points lie on a line:
The slope of the line would be solved using the slope formula as explained below:
Slope (m) = change in y / change in x = (-5 - 4) / (-4 - 3)
m = -9 / -7
Slope (m) = 9/7.
Therefore, the slope is identified as:
a. 9/7.
