the age of A Is five years more than that of B.5 years ago, the ratio of their age was 3:2. find their present ages

A: 20 years old

B: 15 years old

Step-by-step explanation:

Let the present age of A be A, and the age of B be B.

5 years ago, their ages are A-5 and B-5 respectively.

So, we can write 2 equations from the given info.

A - B = 5 (1)

(A-5) / (B - 5) = 3/2 (2)

From equation (1),

A = 5 + B(3)

Substitute (3) into (2).

(5+B -5) / / (B - 5) = 3/2

B / (B-5) = 3/2

cross multiply:

3 (B-5) = 2B

3B - 15 = 2B

3B - 2B = 15

B = 15

Now substitute B = 15 into (3).

A = 5 + 15

A = 20

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

correct answer:

b.(19,-2)
