Answer:
Step-by-step explanation:
The correct answer of this question is the last one which D
(10 + 14 + 8 + 16 + 12 + x ) /6 = 13
(60 + x) / 6 = 13
60 + x = 13 * 6
60 + x = 78
x = 78 - 60
x = 18 <=====
Answer:
You can substitute
4
as
x
in the first equation because
x
and
4
are equal.
2
(
4
)
+
y
=
29
8
+
y
=
29
y
=
21
Step-by-step explanation:
Set them into slope-intercept forms of equations then set those equations equal to each other and solve for x and y. y = 34x - 5 and y = -14x+3. Set those equal to each other, solve for x to get x = 1/6. Sub in that x value to get y = 2/3. The point where they intersect is the solution of the system; in other words, where on both lines we have the exact same (x, y) value.
