4. In three years, the price of a new model of an S6-mobile phone will be six more than twice its current price. If the projected price of the new S6 phone is P40,000. 00 what is the algebraic equation to express its current price? 5. Romar is twice as old as Mavic. Jaypee is 2 years older than Romar. Write an algebraic equation showing that twice the sum of Romar and Mavic ages will result to Jaypee's age.

Sagot :

4. Let x be the current price of the S6-mobile phone.

According to the given information, in three years the price will be P40,000.00 and will be six more than twice its current price.

Therefore, the equation can be expressed as:

2x + 6 = P40,000.00

5. Let M represent Mavic's age, Romar's age is 2M, and Jaypee's age is 2M + 2.

To show that twice the sum of Romar and Mavic ages is equal to Jaypee's age, the algebraic equation is:

2(2M + M) = 2M + 2
