Answer:
Commutative Property of Addition
Answer:
x = 9
Step-by-step explanation:
Opposite sides of a parallelogram are equal.
16x - 15 = 11x + 30 Subtract 11x from both sides
16x - 11x - 15 = 30 Combine the left
5x - 15 = 30 Add 15 to both sides
5x = 30 + 15 Combine the right
5x = 45 Divide by 5
5x/5 = 45/5
x = 9
Answer:
18 stars
Step-by-step explanation:
We can use a ratio to solve
9 stars x
--------- = -----------
2 hearts 4 hearts
Using cross products
9*4 = 2x
36 = 2x
Divide by 2
36/2 =2x/2
18 =x
18 stars
Given:


Since R is the midpoint of the line, we can set XR equal to RY and solve for x.





Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:


Let's find RY now:



Since we know that:

We can plug in our answers:

Final answer:
