Answer: -2/3
-1/15 + (-3/5)
-1/15 - 3/5
-3/5 = -9/15
-1/15 - 9/15
-10/15
-2/3
Perimeter of a square = 4 * each side
so, in the given case 4 * lenght of each side = 272 yards
so, each side = 272/4 = 68 yards
Answer:
Step-by-step explanation:
<u>Possible number of pairs of given cards:</u>
<u>Number of sums with odd score, two odd numbers added to an even number from each box:</u>
- 2*1 + 1*2 = 4 (pairs of 3 and 5 with 2 or pairs of 9 and 3 with 4)
<u>Required probability:</u>
Let Poly = X
Andy gets twice as much as Poly so Andy = 2X
Pheobe gets three times as much as Andy, so she is 3(2x) = 6X
Now add them together to equal 270:
X + 2X + 6X = 270
Simplify:
9X = 270
Divide both sides by 9:
X = 270 /9
X = 30
Poly = X = 30
Andy = 2X = 2(30) = 60
Pheobe = 6X = 6(30) = 180
The slope is 2 because if you put the change in y over the change in x you get 2/1 and the 1 on the bottom don’t make a difference so it’s just 2
