Surface area define or calculate the exact space that each face of the said shape is taken up while the volume is how much space is inside the said object. The area use the unit that is squared because it only measured 2 face in the shape while the volume measures 3 faces in the object. an example of an area is a card board area, while the volume is the glass of water.
2 x - 5 y = 18 / * 4
3 x + 4 y = 4 / * 5 ( we will use the addition method )
--------------------------
8 x - 20 y = 72
+
15 x + 20 y = 20
-----------------------
23 x = 92
x = 92 : 23
x = 4
8 - 5 y = 18
- 5 y = 18 - 8
- 5 y = 10
y = 10 : ( - 5 )
y = - 2
Answer:
( x, y ) = ( 4, - 2 )
MJH = 120
Let TJH = x
You’re told MJT is 4 times TJH
So you have 4x + x = 120
Simplify: 5x = 120
Divide both sides by 5:
X = 24
TJH = x = 24 degrees.
JT is a bisector so both TJH and TJA are the same. So TJA is also 24 degrees
So MJA = 120 - 24 - 24 = 72
MJA = 72 degrees
Answer: x= 0
Explanation
64 = 4^3
4^x+3 = 4^3
X+3 = 3
x =0
