Emmanuel has 745 pictures in his phone. his memory is getting full, so he starts deleting 29 pictures everyday. define each variable and write an algebraic expression to describe the number of pictures left on his phone after any given number of days.

since you're starting with 745 thats your first number and your deleting 25 pitures everyday so your equation would be

745 - 25x

You can use the following expression to represent the problem:

745-29d

745 → Total/starting number of photos that Emmanuel has.

29 → Number of pictures being deleted everyday.

d → Number/amount of days that pictures were deleted.

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'.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
