Answer:
one solution; (x, y) = (4/3, 11/3)
Step-by-step explanation:
The two lines described by the equations have different slopes, so there will be exactly one solution to the system of equations.
__
The slope of the line will be the coefficient of x when you solve for y. In the first equation, the slope is 2. In the second equation, you can solve for y by adding x, and dividing by 2. Then the slope of that line is found to be 1/2.
Lines with different slopes must intersect somewhere. That point of intersection is the (one) solution to the system of equations.
Answer:
Number of self-Help books sold = 252 books
Step-by-step explanation:
Total books sold last week = 1,125
Central angle for the Self-Help slice = 80.64°
Total angle in a circle = 360°
How many of the books sold were Self-Help books?
Number of self-Help books sold =
Central angle for the Self-Help slice / Total angle in a circle × total number of books sold
= 80.64° / 360° × 1,125
= 0.224 × 1,125
= 252
Number of self-Help books sold = 252 books

Step-by-step explanation:
Here you solve for length width and height, which multiplied equal volume. The only constant you have is that the width of the prism is 1/3 of its length.
WIDTH: 3 centimeters
LENGTH: Since the width is 1/3 of the length, 3 is 1/3 of something. So divide 3 by 1/3 to get 9. You can also just multiply 3 by 3.
HEIGHT: The height is half of the width, which is 3. Therefore 3 divided by 2 is 1.5.
Now multiply the values. 3 multiplied by 9 multiplied by 1.5
The answer is 40.5
