Brianna wants to buy some trees for her yard. a local store charges $25 to plant each tree plus a delivery fee of $50. a lawn service charges $35 to plant each tree with free delivery. determine the solution to the system of equation algebraically. show your work, and explain what the solutions means in this context.

175

Step-by-step explanation:

The local store charges 25t+50 and the lawn service charges 35t where t represents the count of trees.

The solution is found when 25t+50 is equal to 35t:

Subtract 25t from both sides:

Divide both sides by 10:

Therefore, t is 5. We just need to find 25t+50 or 35t, which we just determined is equal when t is 5.

35*5=175, meaning the solution is 175. The context is that when you buy 5 trees, both options are equally priced.

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'.
