Josephine is saving money for a new bike and he already saved $17 . Write the integers she should use to represent each entry

1 answer:

5 0

Not sure I understand what it's asking but the formula would be...

x(money) + 17 = Y(price of the bike)

minus both sides to see how much you need left

Answer:

48 cm

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides.

Find the length of the unknown side

Let the unknown length be x cm.

Notice that the sum of the lengths of the unknown side and the side measuring 5 cm I equal to the length of the side measuring 9 cm.

x +5= 9

<em>Subtracting 5 from both sides:</em>

x= 9 -5

x= 4

Add up the lengths of all of the sides to find the perimeter. I will add the lengths starting from the side measuring x cm (or 4 cm), and sum them up in a clockwise manner. This ensures that none of the sides are overlooked.

Perimeter of the figure

= 4 +15 +9 +7 +5 +8

= 48 cm
