Answer:
A part to whole ratio is 5:11
Step-by-step explanation:
There are 5 girls which is a part and 11 which is 5 plus 6 and that is a whole
You can either graph the two lines on an online graphing website and find where they intersect.
If you aren't allowed to do so, just plug in one equation into the other.
y=3x+12, so plug in y into 2y= -x-11.
Then you get 2(3x+12)=-x-11.
Distribute to get 6x+24= -x-11
At this point I hope you can solve for x by yourself, but if you can't, here's how:
7x+24=-11
7x=-25
x=
To find y, plug in x into either equations: <span>2y= -x -11 and y=3x + 12.
</span>You get about -3.714
So coordinate of interesection=
, -3.714
Answer:
A for me beacause i understand quite
Step-by-step explanation:
Hope it helps good day
The area of a rhombus is 1/2 times the lengths of the diagonals
A = (1/2)(AC)(BD)
Since the diagonals bisect each other, and ed = 8, BD must be 16. Substituting in this for BD and the given area (168) we get the following:
168 = (1/2)(AC)16
168 = 8(AC)
21 = AC
