Answer:
The last answer; 12.
Step-by-step explanation:
In order to solve this, use substitution. Since it gives you an equation for y, substitute that equation in the other formula as y. This will give you:
Then simplify:
Since 6x - 6x cancels out, you are left with 12.
The values of the variables x and y in the triangle are 1.25 and 1.75
<h3>How to determine the values of the variables x and y?</h3>
The tringle represents the given parameter
On the triangle, we have the following equivalent ratio
5 : 8 = 5 + x : 10
7 : 8 = 7 + y : 10
These are true because the horizontal lines of the triangles are parallel
So, we have
5 : 8 = 5 + x : 10
Express as fraction
5/8 = 5 + x/10
This gives
5 + x = 6.25
Solve for x
x = 1.25
Similarly, we have
7 : 8 = 7 + y : 10
So, we have
7/8 = 7 + y/10
This gives
7 + y = 10*7/8
Evaluate
7 + y = 8.75
So, we have
y = 1.75
Hence, the values of x and y are 1.25 and 1.75

The formula of a circle is A = pi * r^2
The diameter is 16cm, half of a diameter is the radius.
16/2 = 8
The radius is 8cm
pi (8)^2 or 3.14 (8)^2 = 200.96
Closest answer will be 201 (option C)
Answer:
21,900 planes annually
Step-by-step explanation:
set up a ratio, # planes / time
<u> 150 </u> = <u> x </u>
6 hrs 24 hrs
cross-multiply: 6x = 3600
x = 600; meaning 600 planes per day
multiply 600 by 365 days
21,900 planes over 365 days
