It is the first answer, x=4; y=8
Set up and add equations:
4x+y=24
+ x-y=-4
So 5x=20 (the y’s cancel)
X=4
Then substitute in 4(4)+y=24
16+y=24
Y=8
Answer:
48
Step-by-step explanation:
5(9) + 5(3) - 4(3)
45+15-12
60-12
=48
Answer:
The answer is B.
Step-by-step explanation:
Graph it on Desmos.
<h2><u><em>
PLEASE MARK AS BRAINLIEST!!!!!</em></u></h2>
X and Y are supplementary, that means X + Y = 180.
But we have, X = Y +24, then
X + Y = Y + 24 + Y = 2Y + 24 = 180
Then
2Y = 156
Y = 78
Then X = 78 + 24 = 102.
Answer:
(A)Show that the ratios StartFraction U V Over X Y EndFraction , StartFraction W U Over Z X EndFraction , and StartFraction W V Over Z Y EndFraction are equivalent.

Step-by-step explanation:
In Triangles WUV and XZY:

Therefore:

To show that the triangles are similar by the SSS similarity theorem, we have:

As a check:

The correct option is A.
