Step-by-step explanation:

Let Jack's present age be x

Hence, his fathers present age=4x

Jacks age after 5 years= (x+5)

Jacks Fathers age after 5 years= (4x+5)

We know.. that the difference between their ages fives years later is 10.. hence

4x+5-(x+5)=10

4x+5-x-5=10

3x = 10

x= 3.3 years old...

Hence,

Jacks present age = 3.3 years

Fathers present age= 13.2 years...

Hope it helps .. I know that the answer comes in decimals... but the questions' like that..

Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30
kirill115 [55]

Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n  = 20n^2 -10

10n  - 10n  = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5

The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3. If 600 more people own a
Anuta_ua [19.1K]

Answer:

900

Step-by-step explanation:

The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.

Let the number of people who own a flip phone=x

If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600

To find x, we express the ratio and population as an equality.

5:3=x+600:x

Expressing the ratios as fractions would give:

\dfrac{5}{3}=\dfrac{x+600}{x}

Next, we cross multiply

5x=3(x+600)

Open the brackets by expansion.

5x=3x+(3 X 600)

5x=3x+1800

Subtract 3x from both sides.

5x-3x=3x-3x+1800

2x=1800

Divide both sides by 2

x=900.

Since x=900, the number of people who own a flip phone is 900.
