Answer:
Step-by-step explanation:
BD is the perpendicular bisector of AC because AD = DC and DB⊥AC, therefore AB = BC
- 6x = 9x - 27
- 9x - 6x = 27
- 3x = 27
- x = 9
BC = 9x - 27 = 9*9 - 27 = 81 - 27 = 54
-----------------------
JL is angle bisector of KJM, because KL = ML and KL⊥JK & ML⊥JM, therefore
- m∠KJL = m∠MJL
- 4x + 6 = 3x + 10
- 4x - 3x = 10 - 6
- x = 4
m∠KJL = 4*4° + 6 = 22°
Answer:
BC=54
m<KJL=22°
Step-by-step explanation:
6x=9x-27
27=3x
x=9
9(9)-27=54
BC=54
4x+6=3x+10
x=4
4(4)+6=22
m<KJL=22°

Where:
: Is the lateral area
B: It is the area of the base
Where:
Q: It is the perimeter of the base
h: It's the height
On the other hand:
So, we have:
Answer:
Divided 3 on both sides
X= 243

Answer:
there are 13 people in the group
Step-by-step explanation:
First step is to subtract the one-time fee from the cost
$60 - $8 = $52
Second step is to divide by the cost per person
⇒ $52/$4 = 13
Answer:
32/27
Step-by-step explanation:
Evaluate for x=
8
/9 + 8
/27
8
/9 + 8
/27
=32/27
(Decimal: 1.185185)
8 - 7x^2 + 3 = 4x^2 - 1
8+3-7x^2 = 4x^2-1
11-7x^2 = 4x^2-1
B. Commutative property of addition
We can swap numbers and obtain the same results.
In this case, we swapped 8+3 and added them.
