Answer:

x=12

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

5x+8x+2x =180

Combine like terms

15x = 180

Divide by 15 on each side

15x/15 =180/15

x=12

If 5ex = 300, x = A) ln (300) = 5.703 . . . B) 5 ln (60) = 20.471 . . . C) ln (300)∕5 = 1.140 . . . D) ln (60) = 4.094 . . .
tino4ka555 [31]

Answer:

D) ln (60) = 4.094...

Step-by-step explanation:

Let's solve for x

We'll be careful because it's exponential.

5ex = 300

ex= 300/5

ex= 60

x = e^-1(60)

Let's note that this expression e^-1 is equal to In

x= In (60)

x = 4.0943

So the value of x is equal to 4.0943

Thank you.

PLEASE HELP, GEOMETRY. PICTURE ATTACHED
strojnjashka [21]
This is an isosceles triangle, therefore we have two sides with the same length.
This sides are JM and MK; therefore:
JM=MK

JM=9x-18
MK=3x

Therefore:
9x-18=3x
9x-3x=18
6x=18
x=18/6
x=3

Part A:
Answer:  x=3 

Part B:
JM=9x-18=9(3)-18=27-18=9

Answer: JM=9
