Answer:

the answer is

BC = EF

Let BC = EF = x

AC = AB + BC....................... 1

AC = AB + x ............... 2

From equation 2, AB = AC - x ................. 3

Substitute equation 3 into 1:

AC = AB + BC

AC = AC-x + BC

AC-AC = -c + BC

0 = -x + BC

BC = x

Since AC is greater than AB by a value of x, hence AC > BC

According to the question, we are to complete a 2-column proof to show that the measure of BC is equal to EF:

Given the following:

  • BC = EF
  • Let BC = EF = x

AC = AB + BC....................... 1

AC = AB + x ............... 2

From equation 2, AB = AC - x ................. 3

Substitute equation 3 into 1:

AC = AB + BC

AC = AC-x + BC

AC-AC = -c + BC

0 = -x + BC

BC = x

Since AC is greater than AB by a value of x, hence AC > BC

Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30
gregori [183]
The answer is 5x + 30 = 12x

x - the number of pies

It costs her $5 to make each pie<span>, plus a one-time cost of $30 for baking supplies:
</span>COST: f(c) = 5x + 30

<span>She plans to sell the pies for $12 each:
PROFIT: f(p) = 12x

</span><span>To find the number of pies she needs to sell to break even:
f(c) = f(p)
5x + 30 = 12x</span>

Use the formula A=bh , where A is the area, b is the base length, and h is the height of the parallelogram, to solve this proble
harkovskaia [24]
We know that:

A = 1440
H = 32

So you need to work backwards to find base.

1440 / 32 = 45

We can check our work:

32 x 45 = 1440

B = 45
