Answer:
So x = 20
Step-by-step explanation:
AB + BC = AC sum of a segment is sum of its pieces
AB + AB = AC B is the midpoint, so AB = BC
2x + 2x = 3x + 20 putting in for AB (twice!) and AC
4x = 3x + 20 collect like terms
x = 20 subtract 3x on both sides.

Answer:
-29
Step-by-step explanation:
substitute the y and x values whith there given values
so 1/3-2(3)-4(-1)2
first simplify (-1)2 or (-1)(-1) which is 1 so now the equation is 1/3-2(3)-4(1)
now you must solve all the values that have multiplying involved so you have 1/3-6-4
now subtract 6 and 4 to get 1/3-10
now find the LCD which is 3
multiply the LCD by both terms to get 1-30 which equals -29
X = -5.35

Answer:
4x + 2y = 2
Step-by-step explanation:
8x + 4y = 2 ( divide each term by 2 )
4x + 2y = 1 → (1)
we require a situation where the left side cannot possibly equal the right side.
using 4x + 2y = 2 → (2)
subtract (1) from (2) term by term
(4x - 4x) + (2y - 2y) = 2 - 1 , that is
0 + 0 = 1
0 = 1 ← not possible
thus the system has no solution
