Question

Translate each problem into a mathematical equation.
1. The price of 32'' LED television is P15,500 less than twice the price of the
old model. If it cost P29,078.00 to buy a new 32'' LED television, what is
the price of the old model?

2. The perimeter of the rectangle is 96 when the length of a rectangle is
twice the width. What are the dimensions of therectangle?
​

Answer 1

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Answer:

Answer 1) :-

Let us assume that, price of the old model is Px .

so,

→ Price of 32" LED television = P(2x - 15.500)

A/q,

→ (2x - 15.500) = 29.078

→ 2x = 29.078 + 15.500

→ 2x = 44.578

→ x = P22.289 (Ans.)

Answer 2) :-

Let us assume that, width of the rectangle is x unit.

so,

→ Length = twice of width = 2 * x = 2x unit .

then,

→ Perimeter = 2(Length + width)

A/q,

→ 2(2x + x) = 96

→ 3x = 48

→ x = 16 unit .

therefore,

Width of rectangle = x = 16 units .

Length of rectangle = 2x = 32 units.

Hence, the dimensions of the rectangle are 16units and 32 units.
