According to the Triangle Midsegment Thereom, if the midsegment of a triangle is parallel to a side of the triangle, then the midsegment is half the length of side it is parallel to, therefore...
45=(7x+13)/2
And after that, you continue to solve the problem using Algebra
90=7x+13
77=7x
11=x
I hope this answer was helpful! :)

Anastasy [175]

For this case we must find the unit cost (dollars per pound) of each site and then compare.

We take into account that:

1kg equals 2.205 pounds

So, we have:

Site 1:

C = 2.25 \frac {dollars} {pound}

Site 2:

5kg = 5 (2.205\ pounds) = 11.025 pounds

So, the unit cost is:

C = \frac {14} {11.025} \frac {dollars} {pound} = 1.27 \frac {dollars} {pound}

Thus, the best deal is on site 2.

ANswer:

The best deal is on site 2.
