The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm
Hope this helps :)
9000mm is equivalent to 900cm
It would be
indicating we start at 5 but do NOT include 5, and we keep going onward to positive infinity.
The curved parenthesis tells us not to include the endpoint.
Answer: (1, -4)
Step-by-step explanation: just, go across to the other axis.
The system is comprised of two processes
that go on at the same time:
#1). Do what ever you want to, to get 'x'
on one side of the equation, and
everything else on the other side.
#2). Whatever you do to one side of the equation,
you must immediately do the same thing to the
other side.
That's the system.
Here's how it works: (I can't believe you're in high school math
and you've never seen, studied, or practiced this before.)
You said that 4x - 9 = 2x + 15
and you need to find
what 'x' is.
Subtract 2x from each side: 2x - 9 = 15
Add 9 to each side: 2x = 24
Divide each side by 2 : x = 12 .
