Answer:
Angle3 and Angle7
Step-by-step explanation:
You have to get the x to one side so you'll subtract 3x from -6x and 3x from 3x, the 3x will cancel out and -6x - 3x is -9x-7=11, you have to add 7 from both sides the 7+7 cancels out and also add 11+7 which leaves -9x=18, you have to divide -9x/-9 and do 18/-9, which gets you x=-2. Here's the work shown if you didn't what i said...
-6x-7=3x+11
-3x -3x
-9x-7=11
+7 +7
-9x=18
-9 -9
x=-2

Answer:
-0.5 degrees Celsius
Step-by-step explanation:
Since the top of the mountain's temp change was -2.5, simple multiply by 1/5 or divide by 5 to get -0.5 and your lower mountain's change of temperature.
Length=(x+3)
Breadth=(x-3)
Height=(2x-5)
