Answer:
x = 1.25
y = 1.75
Step-by-step explanation:
Since, the line that is 8 units long is parallel to the line that is ten units long.
Therefore, both the triangles are similar by AA postulate.
Corresponding sides of of the similar triangles are in proportion.
Therefore,
Answer:
18.5
Step-by-step explanation:
First find the area of the two triangles.
1.5 * 1.5 = 2.25
Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5
Finally, find the area of the floor: 1.5 * 2.5 = 3.75
2.25 + 8.5 + 7.75 = 18.5
Answer:
69%
Step-by-step explanation:
Since we only have two options, rain or not rain, they have to add to 100%
100 -31 = 69
So not raining is 69%

Answer:
The y-value is -20
Step-by-step explanation:
So let's solve this by Elimination method;
-2(4x + 5y = -12)
4(2x + 3y = -16)
Let's Distribute;
-8x - 10y = 24
8x + 12y = -64
So x cancels out because -8 + 8 = 0
-10y + 12y = 2y
24 - 64 = -40
2y = -40
Divide both sides by 2;
y = -20
Now lets plug in y to find the value of x;
4x + 5(-20) = -12
4x - 100 = -12
Add 100 to both sides;
4x = 88
Divide both sides by 4;
x = 22
