Step-by-step explanation:
(3x + 2y =19)(3)
-9x + 8y =-29
9x + 6y = 57 <em><u>NOTE</u></em><em><u>:</u></em> we cross here 9x in first
-9x + 8y = -29 we cross here - 9x in second
Since 9x and - 9x are opposite
___________
6y +8y = 57 - 29
14y = 28
Y=28/14
Y=2
Replace y in second equation of this system:
-9x + 8y = - 29
-9x +8(2)= - 29
-9x + 16 = - 29
-9x = -29 - 16
-9x = - 45
X= -45/-9
X=5
Hope this helps..
Answer: BC=8 units
Step-by-step explanation:
So in this figure, this triangle, that is a parallelogram named DFCE , and one of their property three yeti you add learn you learned is that a parallelogram has like rectangle two sides per two that are parallel and have the same measure ( but you can also use the little lines that show who is the same as who ) in this one you can write an equality: CE=FD=4. Then there is the same two lines on the EB segment so EB=4 . Then we can write that BC= BE + EC
BC= 4+4
BC= 8 units

Answer:
x = 20
Step-by-step explanation:
The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)
So, set them equal to each other and solve.
3x + 50 = 6x - 10
SUBTRACT 3x from both sides.
50 = 3x - 10
ADD 10 to both sides.
60 = 3x
DIVIDE both sides by 3.
20 = x
