The number of pledges that Melissa collected for this year's charity walk is 8 less than half the number of pledges she collected last year. Which expression represents the number of pledges she collected this year?

1/2x - 8

Step-by-step explanation:

Let

x = number of pledges she collected last year

The number of pledges that Melissa collected for this year's charity walk is 8 less than half the number of pledges she collected last year.

Number of pledges she collected this year = 1/2x - 8

The expression which represents the number of pledges she collected this year = 1/2x - 8

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
