Problem Card 2
Elena is designing a rectangular picture
frame with a lace border. What widths
can Elena choose for the frame? Write an Inequality.
• In order to fit nicely on her desk, the
frame needs to be 7 centimeters in
length.
• She only has 65 centimeters of lace
available to use for the border.

The inequality w+14≤65 represents the situation.

Step-by-step explanation:

Given,

Length of frame = 7 centimeters

Lace available to use = 65 centimeters

Let,

Width of frame = w

As the frame is rectangular, we will use perimeter of frame.

Perimeter would be less than or equal to 65cm.

The inequality w+14≤65 represents the situation.

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
