Answer:
x
=
12 and y
=
1
Explanation:
Given equations are:
(1) ------ 1
3
x
−
y
=
3
(2)------
2
x
+
y
=
25
Multiply (1) by 3 to eliminate the fractional part,
(1) ------- x
−
3
y
=
9 ⇒
x
=
9
+
3
y
-------- let this be equation (3)
Now substitute this value of
x
from (3) in equation (2),
(2) --------- 2
(
9
+
3
y
)
+
y
=
25 ⇒
18
+
6
y
+
y
=
25 ⇒
7
y
=
25
−
18 ⇒
y
=
7
7
Therefore,
y
=
1
Substituting this value of
y
in equation (3),
x
=
9
+
3
×
1
x
=
9
+
3
Therefore,
x
=
12
So we have the values of
x and y as,
x
=
12
and
y
=
1

Answer:
B: 8(N - 17) = 30
Step-by-step explanation:
Since the wording multiplies the difference by 8, the appropriate choice is B.
__
A: "the difference of the product eight times a number and seventeen" It is less ambiguous if you can word it as "the difference of seventeen and the product of 8 and a number is negative 30".
C: "The difference of eight times a number and seventeen times the same number is thirty."
Answer:
F is the midpoint of AA' because Line E G bisects AA'
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
When reflecting a figure, the image is congruent to the pre-image.
A reflection maps every point of the pre-image to an image across a fixed line. The fixed line is called the line of reflection.
The distance of each point of the pre-image from the line of reflection will be the same as the distance of each point of image from the line.
In this problem the line of reflection is E G
The distance A F is equal to the distance A'F
Point F is the midpoint segment A A'
so
Line segment E G bisects segment A A'
therefore
F is the midpoint of A A' because Line E G bisects A A'
