D: because if you take 9.50-7.50=2 you would get p=price or the price of the pen.
Hope I helped=)
#2- yes because both can be divided or multiplied for example 3 and 9, u can multiply 3x3 to get 9 since the dilation is 3 then yes it is similar triangles
Answer:
3.25
Step-by-step explanation:
I plugged in 5 for x and got 3.25 when I solved
You would multiply all of the numbers to get your answer so it would be 4*5*6*8 which would get you 960.
Answer:
x is 72 degrees
Step-by-step explanation:
To find the measure of x, you need to know the sum of the interior angles of the pentagon.
Sum = (n - 2) x 180
Sum = (5 - 2) x 180
Sum = 3 x 180
Sum = 540
Now divide this by 5, the number of sides
540/5 = 108 degrees for each angle of the pentagon.
To find the measure of x, look at the opposite angle, which is 108 degrees
180 - 108 = 72
The measure of angle x is 72 degrees.
