The ratio of aziz's money to osman's money was 2: 1 at first. after aziz spent $10 ratio became 4: 3. how much money did each boy have at first

Aziz's money was $30

Osman's  money was $15

Step-by-step explanation:

Let

x-----> Aziz's money at first

y-----> Osman's  money

we know that

------> equation A

-----> equation B

substitute equation A in equation B and solve for y

Find the value of x

therefore

At first

Aziz's money was $30

Osman's  money was $15

step-by-step explanation:

this is not a question

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
