Answer:
Step-by-step explanation:
Find out the length of each side. For the slanty sides, you can do this by using the formula
For the straight sides (like the one on the bottom and the one on the left), just use simple subtraction.
Add up all 4 sides and you get the perimeter. You should get 20, 15, 
and 
. The total is 35 + 
.
Answer:
15
Step-by-step explanation:Addentitive property states that any number added with 0 is the original number. so, 15+0=15
Answer:
Solutions to equations of this form are ordered pairs (x, y), where the coordinates, ... When given linear equations with two variables, we can solve for one of the ... Since the solutions to linear equations are ordered pairs, they can be graphed using the rectangular coordinate system. ... 32. x−y=0 x − y = 0 ; {10, 20, 30}. Find

Answer:
90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World
Step-by-step explanation:
Since this is a problem of proportion we can use the Rule of three to solve this. We do this by multiplying the diagonal available values and dividing by the third value in order to get the missing variable, which in this case would be the number of stamps in the other country. Like so...
1.5 <=====> 135 stamps
1.2 <=====> x stamps (United States)
(1.2 * 135) / 1.5 = 108 stamps (United States)
1.5 <=====> 135 stamps
1 <=====> x stamps (Canada)
(1 * 135) / 1.5 = 90 stamps (Canada)
Finally, we can see that Katie had 90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World. All creating a ratio or 1:1.2:1.5
