Step-by-step explanation:
Answer:
B
Step-by-step explanation:
4 (x) + 2 (-1) = 2 (-x) + 6(1)
4x + -2 = -2x + 6
I believe you meant to have...
4x + 17 = 5x + 6...
Move the 4x to the right by subtracting it from both sides which in result you get...
17 = x + 6
Then you want to subtract 6 from the right to the left so you get...
11 = x
OR
If you meant 4 * 17 = 5x + 6 then what you do is multiply the left side which in turn gets...
68 = 5x + 6
Subtract six from the right to the left and you get...
63 = 5x
Divide by 5 then you get..
x = 63/5 or you can also say x = 12.6
Answer: x=40 y=140
Step-by-step explanation:
To work out x:
The angles in a triangle always add up to 180.
You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.
To work out y:
Angles on a straight also add up to 180.
So as you have figured out what x is (40) you would take it away from 180 to give you y.
180-40=140
Hope this helps :)
