Answer:
46.3
Step-by-step explanation:
Mean is the average of all values. You add all the values on the table and divide them by the amount of values (here there are 10 land animals so you would divide by 10).
Add all the sides n u will get ur answer
Answer: The Perimeter of the rectangle, P= 16v −24w
Step-by-step explanation:
Perimeter of a rectangle = 2( L +W) = 2L + 2W
The width of a rectangle is given as (3v-3w) centimeters,
its length is given as (5v-9w) centimetres
The Perimeter,P will now be = 2L + 2W
P=2( 3v-3w) + 2( 5v-9w)
P=6v −6w + 10v - 18 w
adding like terms
P=6v + 10v −6w −18 w
P= 16v −24w

the answer to that is sometimes
Answer:
Y=4 X= -6 or (-6,4)
Step-by-step explanation:
Okay so
3x+10y=22
-3x-8y=-14
- basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 0
- 10y minus 8y gives us 2y.
- 22 minus 14 gives us 8
3x+10y=22
<u>-3x-8y=-14</u>
0+2y=8
Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.
From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.
y= 4
Now we can fill in. You can pick any equation for this but I'm going to chose the first one.
3x+10y=22
we can fill in 4 for y
3x+10(4)=22
3x+40=22
Next we are going to subtract 40 on both sides.
3x+40=22
-40 -40
3x= -18
Next, we're going to divide -18 by 3.
The 3s cancel out leaving us x. -18 divided by 3 is -6.
x= -6
Hope this helped!! :)
