Answer:
y= -6
Step-by-step explanation:
-2y - 5y= -7y
-7y=42
42/-7=
y= -6
Let's write out the problem with the triangles as "x" and the ovals as a number. Since there are 3 triangles and 5 boxes in the first box, the first box would be:
3x+5
In the other box, there are 11 ovals, so:
11
With this, they are equal, so:
3x+5=11
To solve this, move the 5 over onto the other side by subtracting 5 from each side:
3x+5<em>-5</em><em> </em>= 11<em>-5</em>
Then you have:
3x = 6
Now, divide doth sides by 3 to isolate x:
3x/3= 6/3
Now you're done!
<u><em>x=2</em></u>
Hope that helps.
A) two factors- 2 (1,2)
b) four factors- 6 (1,2,3,6)
c) five factors- 16 (1,2,4,8,16)
8+4=12
9+7=16
12^2=144
16^2=256
144+256=400
square root of 400 is 20
therefore the distance from (8, -7) to (-4,9) is 20.
The answer is Figure D, because a polygon has to have <em>all</em> actual sides and no curves.
