<h3>
Answer: 10 cm (choice A)</h3>
====================================================
Explanation:
One equation we could solve is
x/2.5 = 30/7.5
Note the x/2.5 has us dividing the vertical sides, while 30/7.5 is the same idea for the horizontal sides. The order is large over small. You could do small over large, but make sure you keep both sides consistent.
Solving for x leads to...
x/2.5 = 30/7.5
x*7.5 = 2.5*30
7.5x = 75
x = 75/7.5
x = 10 (choice A)
There are many other possible equations that lead to the same answer. One other possible equation is x/30 = 2.5/7.5
These proportions are possible due to the fact we have similar triangles.
They would each receive 1/6 of the whole pie.
If you are trying to simplify 36(pi)/4, then 9(pi) would be what you want because it is the simplest form of that fraction. It also depends on the answer choices. Sometimes they want simplest form and other times they’ll have you leave the fraction as is. Typically simplifying completely is your best bet though.

Answer:2m/s
Step-by-step explanation:
Velocity=distance÷time
Velocity=8÷4
Velocity=2m/s
Answer:
y=2
x=4
Step-by-step explanation:
So for a y=2 then y=2x-6
We already know the value of y, 2
To find the value of x you substitute the y value into the second equation
So 2=2x-6 (then move -6 to the other side of the equation, +6)
8=2x (move 2 to the other side, ÷2)
So x=4
I hope this helped :)
