Answer:
x = -3 and y = -2
Step-by-step explanation:
It is given that,
-7x + 6y = 9 ----(1)
-2x - 5y = 16 -------(2)
<u>To find the solution of given equations</u>
eq(1) * 2 ⇒
-14x + 12y = 18 ------(3)
eq(2) * 7 ⇒
-14x - 35y = 112 ---(4)
eq (3) - eq(4) ⇒
-14x + 12y = 18 ------(3)
<u>-14x - 35y = 112 </u> ---(4)
0 4y = -94
y = 94/(-47) = -2
Substitute the value of y in eq (2)
-2x - 5y = 16 -------(2)
-2x - 5*-2 = 16
-2x +10 = 16
-2x = 6
x = 6/-2 = -3
Therefore x = -3 and y = -2
Hey there!
19 is rounded to 20
120 divided by 6=20
20 is your answer
Hope this helps!
Answer:
The answer is C
Step-by-step explanation:
<em>Answer</em><em> </em><em>is</em><em> </em><em>-220</em>
<em>if</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>any</em><em> </em><em>doubts</em><em> </em><em>see</em><em> </em><em>the</em><em> </em><em>image</em><em> </em>
Since A is the midpoint of BC, we can assume BA and AC are equal to each other.
We also know that BC = BA + AC = 23 + 23 = 46
