A man is 13 times as old as his son is. In 10 years he will be 3 times as old as his son is now. How old are they now?
valkas [14]

Answer:

the son is 2

man is 26

+10 yrs

son=12

man=36

Step-by-step explanation:

Let the son's age be x.

Then the father's age is 13x.

In ten years their ages will be (x+10) and (13x+10).

(13x+10)=3(x+10)

13x+10=3x+30

10x=20

x=2

The son is 2 years old.

Cristiano is saving money to buy a bike that costs $189, He saved $99 so far. He plans on saving $10 each week. In how many week
yuradex [85]

Answer:

Cristiano will have enough money to buy bike in 9 weeks.

Step-by-step explanation:

Given:

Cost of the bike = $189

Money saved = $99

Money saving each week = $10

We need to find the number of weeks will he have money to buy bike.

Solution:

Let the number of weeks be 'x'.

Now we can say that;

Money saved  plus money saving each week multiplied by number of weeks is equal to cost of the bike.

framing in equation form we get;

99+10x=189

Subtracting both side by 99 using subtraction property of equality we get;

99+10x-99=189-99\\\\10x=90

Dividing both side by 10 using division property of equality we get;

\frac{10x}{10}=\frac{90}{10}\\\\x=9\ weeks

Hence Cristiano will have enough money to buy bike in 9 weeks.

Direct, inverse, or neither?: xy = 15
timama [110]

Answer:

Well, to be perfectly honest in my humble opinion, of course without offending anyone who thinks different from my point of view but also by looking into this matter in a different perspective and without condemning one's view and by trying to make it objectified and considering each and everyone's valid opinion, I honestly believe that I completely forgot what I was going to say.
