Answer:
None
Step-by-step explanation:
No solutions exist for the system of equations because the system is illogical: 3x+y=3x+y, but 18≠16.
Answer:
5 = x
Step-by-step explanation:
5 divided by 2 = 2.5
12.5 divided by 2.5 = x = 5
Answer:
The correct answer is 10 blocks east
Suggestion:
I suggest using a graph. It is much easier. just start at the center (0,0) and move 10 left, 10 down, 10 up, and then you can see you just need to go 10 right to get back to the center, or in this situation The Pizza Parlor.
Answer:
Perimeter = 
Step-by-step explanation:
Width of the rectangle has been given as
.
Convert the statement into the algebraic expression,
"Length of the rectangle is twice the width"
Length = 2(Width)
= 
= 
Since perimeter of a rectangle is given by the expression,
Perimeter = 2(Length + Width)
By substituting the values of length and width in the expression,
Perimeter = ![2[(5-\frac{1}{4}x)+(10-\frac{1}{2}x)]](https://tex.z-dn.net/?f=2%5B%285-%5Cfrac%7B1%7D%7B4%7Dx%29%2B%2810-%5Cfrac%7B1%7D%7B2%7Dx%29%5D)
= 
=
Therefore, expression representing perimeter is
.
Answer:
Step-by-step explanation:
The printer charges a $27 set-up fee, plus $0.75 for each poster. The set up fee is constant.
The cost y in dollars to print x posters is given by the linear equation
y=0.75x+27.
a) To find the cost, y in dollars to print 50 posters, we will substitute 50 for x in the given linear equation. It becomes
y=0.75x+27
y = 0.75 × 50 +27
y = 37.5 +27 =$64.5
b) To find the cost, y in dollars to print 100 posters, we will substitute 100 for x in the given linear equation. It becomes
y=0.75x+27
y = 0.75 × 100 +27
y = 75+27 =$102
