Answer:
60,000
Step-by-step explanation:
Let the total people in the household be 100%
If 80 percent of the households have cable television, 60 percent of the households have videocassette recorders and the number of households that have both cable television and videocassette recorders is 'x' percent. The number of households having ONLY cable television will be 80-x while households having ONLY videocassette will be 60-x.
To get x, we will have;
80-x + 60-x + x = 100
140-x = 100
x = 140-100
x = 40
This shows that 40% of the households have both cable television and videocassette.
If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be 40% of 150,000
= 40/100 × 150,000
= 60,000
Number of households that owns both television and videocassette could be from 60,000.
Alternate interior angles are those which are on the inside of the parallel line and are alternate to eachother.

Answer:
There will be an infinite number of solutions.
Step-by-step explanation:
From the given system of equations, we have to find the solution.
The equations are
........... (1) and
- 3x + 4y = - 20 .......... (2)
Now, simplifying the equation (1) we get
4y = 3x - 20
⇒ - 3x + 4y = - 20
which is nothing but the equation (2).
Therefore, the system of equations (1) and (2) are the same straight line.
Hence, there will be an infinite number of solutions. (Answer)
