pls help! tysm
Answer:
x = 30.
Step-by-step explanation:
The angle next to the 60 degree angle = 180 - 60 = 120 degrees (adjacent angles are supplementary).
Let the angle just above 3x be y. The sum of 3x and y = 120 degrees (as opposite angles of a parallelogram are equal).
We have the following equations.
3x + y = 120............(1)
2x + 90 + y = 180
2x + y = 90.............(2)
Subtracting, (1) - (2):
x = 30.
Answer:
The answer is -4.
Step-by-step explanation:
Start with distribution: -6x+9=33
Additive Inverse of 9: -6x+9=33
-9 -9
----------------
Divide both sides by -6: -6x = 24
x=-4
The solution to the expression (-0.75x + 6) -(2.5x -1.9) is -3.25x + 7.9
From the question, we have the following parameters that can be used in our computation:
(-0.75x + 6) -(2.5x -1.9)
Open teh brackets
So, we have
(-0.75x + 6) -(2.5x -1.9) = -0.75x + 6 -2.5x + 1.9
Evaluate the like terms
So, we have
(-0.75x + 6) -(2.5x -1.9) = -3.25x + 7.9
Hence, the solution is -3.25x + 7.9

problem given: (-0.75x + 6) -(2.5x -1.9)
distribute: -0.75x+6 -2.5x-1.9
combine like terms: -0.75x-2.5x= -3.25x ; 1.9+6=7.6
solution: -3.25x+7.6
