Answer and Step-by-step explanation:
The cost of all the 6 magazines are: 6x
The cost of all the 9 newspapers are 9(x-3)
So, the total cost is the sum of all the items:
6x + 9(x-3) = 51
6x + 9x - 27 = 51
15x = 78
x = 5.2
Since the cost of one magazine is $x, the cost will be $5.20.
Answer:
Use a compass to draw two equal arcs ...
Step-by-step explanation:
The attached diagram shows the construction of an angle bisector. First you draw arc DE, then arcs from D and E with the same radius that cross at F.
So, the step on your list is, "use a compass to draw two equal arcs from the intersection points of a previous arc and the legs."
Answer:
A. the first one is true because when x = 5, 4x - 1 equals 19. The second inequality doesn't allow for it to equal 19.
B. 9 is the value that makes the equation true. See below for work to show.
Step-by-step explanation:
4x -1 </= 19 is true because it's "less than or equal to" and when you change the x to 5, the answer is exactly 19. 4(5) - 1 = 19. The other sentence is "4x - 1 is less than 19", and that means it can't equal 19 for that sentence to be true.
Math + words = confusion sometimes. Does that make sense?
------------------------------------
Now let's solve
5x + 2 = 47
Subtract 2 from both sides
5x = 45
divide both sides by 5
x = 9
