Answer:
x = 3
Step-by-step explanation:
The two triangles at the left have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 6x−2.
Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 9x−11.
So:
6x − 2 = 9x − 11
9 = 3x
x = 3
54/72 gets reduced to 27/36 by the number 2 :)
Answer:
Let the number of hours traveled by train be "x".
The x = the number of hours traveled by plane.
-------------------------------------------------
Equation:
train distance + plane distance = 1300 miles
50x + 275x = 1300
x(325) = 1300
x = 4 hours

Answer:
(5,20)
Step-by-step explanation:
2x + 2(4x) = 50
2x + 8x = 50
10x = 50
10x/10 = 50/10x
x = 5
2(5) + 2y = 50
10+ 2y = 50
-10. -10
---------------
2y = 40
2y/2 = 40/2
y = 20
