Answer:
x=71
Step-by-step explanation:
180-38= 142
142/2= 71
it looks like x and the blank space are the same size
A. 10.4 meters
B. 9.3 meters
C. 10.3 meters
Answer:
The width of the piece of construction paper is 6.75 inches.
Step-by-step explanation:
The area of the paper = 
sq inches
The length of the paper = 
in
Let the width of the paper = w inches
Now, AREA OF THE PAPER = LENGTH x WIDTH
or, 65.25 sq. inches = 9. 66 in x w in
⇒ 65.25 = 9.66 x w
or, 
or, w = 6. 75 inches
Hence, the width of the piece of construction paper is 6.75 inches.
So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
or 
Step-by-step explanation:
Substitution means plugging in one variable's value that consists of the opposite variable. Because 
is already specified, you can plug it into the second equation's 
value. After doing that, it looks like this:
Then you would distribute the 
across the parentheses next to it, like this:
Then, add like terms, like this:
Then divide both side by 
to isolate 
.
Now, you can plug 
() into either equation, but the first one seems simpler so you would pick that. It would look like this:
Solving would look like this:
So the answer is or .
