Jamiya and jmarques are having a competition to see who can read more books. jamiya reads 28% fewer books than j'marques. j'marques reads x books. write an expression to represent the number of books that jamiya reads

0.72x

Step-by-step explanation:

28% (of x) fewer than x will be ...

... x - 0.28·x = x(1 -0.28) = 0.72x

Of course, you know that 28% = 28/100 = 0.28.

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".

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'.
