Answer:

total sky divers is 25

Step-by-step explanation:

60% = 15 skydivers

divide by 6 both sides

10% = 2.5

times by 4 both sides

40%=10

_________

60%+40%=100%

15+10=25

What is the solution of two thirds x=12
joja [24]
Hi there!

To solve this problem, we need to simplify. 

2/3x = 12

To isolate x, we should multiply both sides of the equation by the reciprocal of 2/3 to make x equal to a value:

Reciprocal of 2/3 = 3/2

x = 12 * 3/2
x = 18 

Hope this helps!

Solve:<br><br> (15/x)+(9x-7)/(x+2)=9
hram777 [196]

Answer:x=3

Step-by-step explanation:

D( x )

x+2 = 0

x = 0

x+2 = 0

x+2 = 0

x+2 = 0 // - 2

x = -2

x = 0

x = 0

x in (-oo:-2) U (-2:0) U (0:+oo)

(9*x-7)/(x+2)+15/x = 9 // - 9

(9*x-7)/(x+2)+15/x-9 = 0

(x*(9*x-7))/(x*(x+2))+(15*(x+2))/(x*(x+2))+(-9*x*(x+2))/(x*(x+2)) = 0

x*(9*x-7)+15*(x+2)-9*x*(x+2) = 0

9*x^2-9*x^2+8*x-18*x+30 = 0

30-10*x = 0

(30-10*x)/(x*(x+2)) = 0

(30-10*x)/(x*(x+2)) = 0 // * x*(x+2)

30-10*x = 0

30-10*x = 0 // - 30

-10*x = -30 // : -10

x = -30/(-10)

x = 3

x = 3

We have to find the GCF (Greatest Common Factor) of 48 and 42 here... 

Factors of 48:
1,2,3,4,6,8,12,16,24,48

Factors of 42: 
1,2,3,6,7,14,21,42

The largest common factor of these two numbers is 6. 


So, there can be a maximum of 6 members in the club.. 

Hope this helped!

From the graph we observe:  
If x = 0 then y = 1/2    (because  e⁰ = 1)

\displaystyle \bf \\&#10;\Longrightarrow~~\boxed{\bf y =  \frac{1}{2} e^x}
