To solve the problem we must know about the Ratio.
<h2>What is Ratio?</h2>
A ratio shows us the number of times a number contains another number.
The length of the living space, in reality, is 21 meters.
Given to us
- The scale is given as 2 centimeters equals 2.5 meters.
To find
- the actual length of the living space if the length of the scale drawing is 16. 8 centimeters
<h3>Scale ratio</h3>
As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as
<h3>Length of the living space</h3>
Using the same scale ratio,
Hence, the length of the living space, in reality, is 21 meters.

Answer:
11 and 23
Step-by-step explanation:
Answer:
first number=2
second number=-5
Step-by-step explanation:
first number= a
second number= b
we have the following equations
7a+3b=-1 equation 1
a+b=-3 equation 2
using equation 2 we have
a=-3-b
using equation 1 we have
7(-3-b)+3b=-1
-21-7b+3b=-1
-4b=20
b=-20/4=-5 = second number
a+(-5)=-3
a-5=-3
a=-3+5
a=2= first number
