Answer:

Function is h(s) = 40-2s

H(2) = 40-(2)(2)

H(2) = 40-4 = 36

Because the function represents height and time, we can say after 2 seconds the height in feet is 36. --> For H(2)

We need to set 40-2s = 30 for h(s)=30

30-40 = -10

-2s = -10 Divide both sides

s = 5

Divide 735 in the ratio 3:2
Irina18 [472]
First add the 2 numbers in the ratio:

now multiply 147 by 3 and then by 2 and that will be the ratios:

147 * 3 = 441

The sum of Ali and Mel's age is 39. If Mel is 3 years younger than twice Ali's age, how old is Mel?
olga55 [171]

Answer:

Age of Mel is 25 years.

Step-by-step explanation:

It is given that,the sum of Ali and Mel's age is 39. If Mel is 3 years younger than twice Ali's age.

Let 'x' be the Ali's age  and 'y' be the Mel's age

<u>To find the value of x and y</u>

sum of Ali and Mel's age is 39

⇒ x + y = 39    ------(1)

  Mel is 3 years younger than twice Ali's age

⇒ y = 2x - 3   -------(2)

⇒  2x - y = 3  -----(3)

(1) + (3) ⇒  

 x + y = 39

2x - y = 3

----------------

3x   = 42

x = 42/3 = 14

y = 2x - 3 = 14*2 - 3  = 25

Therefore the age of Ali = 14

Age of Mel = 25
