Answer:

49

Step-by-step explanation:

Product of GCD and LCM = Product of the 2 numbers

Product of GCD and LCM = 7 × 140 = 980

One number is 20 so let the other number be N

20×N=7×140

20N=980

2N=98

N=49

so the other number is 49

Answer:

49

Step-by-step explanation:

hello :

let : gcd =D    and  lcm = M    two numbers are : a , b

D×M =a × b

in this exercice : D=7    M=140    b=20   calculate the other number : a

7×140 = a × 20

so : a= 7×140/20 =49

Answer:

a)  W(x)  =  2, 000  - 275 x  represents the given situation.

b) The cost of the computer after 6 years is $350.

Step-by-step explanation:

Initial worth of the company = $2,000

Depreciation each year = $275

Let, W(x) represent the worth of the computer in x - th year.

So, according to the question:

a)   W(x)  =  2, 000  - 275 x  represents the given situation.

b)  Solving W(x) for x = 6, we get

    W(6)  =  2,000  - 275(6)  = 2, 000  -  1,650

              = 350

⇒W(6)  = $350

Hence, the cost of the computer after 6 years is $350.

Answer:

Reminder that is this form  a(b)^x  where  a > 0

When   b > 0  but < 1 that is a decay function

When   b > 1 than its a growth function

Step-by-step explanation:

So following this you can figure out the answer

g(x)=0.3(x)      

this is neither since there is no exponent (linear)

H=72(56)^t    

this is growth since b  = 56

A=(43)^t        

this is growth since b  = 43 ("a" is understood as "1")

H=5.9(0.82)^t      

this is decay since b =  0.82

y=0.8(3.6)^t      

this is growth since b = 3.6

f(t)=0.72(15)^t    

this is growth since b  = 14  

A=49(8)^t      

this is growth since b  = 8

meriva

Answer:

x= 51

Step-by-step explanation:

-17=x/-3

(-3)-17=(x/-3)(-3)

51=x

Multiply the denominator of the fraction on both sides of the equation to isolate the variable.
