Step-by-step explanation:
3 (2x + 4y = 1)
2 (3x - 5y = 7)
=> 12y = 3
-10y = 14
22y = -9
divided bothsides
y = -9/22
To find x
substitute Y= -9/22
into 2x + 4y = 1
2x + 4(-9/22) = 1
2x -18/11 = 1
2x= 1 + 18/11
2x = (11 + 18)/11
2x = 29/11
x = 29/11/2
x= 29/22
Answer:
No
Step-by-step explanation:
To find out if this is a right triangle, we can use Pythagorean Theorem. All right triangles follow the Pythagorean Theorem. In this case, the legs of the figure are 18 and 35 (a and b) and the hypotenuse is 41 (c).
Now, we plug in values and simplify.
As you can see, 1449 is not equal to 1681, so this triangle is not a triangle triangle.

1/2 = 18 cut
Cut= 1/36
So if victor rides for time t+ 1/36
Alex rides for t
D= 18 (t + 1/36) = 24 t
18 t+ 18/36 = 24 t
6 t = 1/2
T = 1/12 hour = 5 minutes
1. D. The triangles have two given sides with an included angle, so the postulate would be SAS.
2. A. The triangles have three given sides, so the postulate would be SSS.
