At the beginning of the bake sale merry set aside two pies for herself Kate bought half of the remaining pies for a birthday par
nirvana33 [79]
So.. .at the beginning of the sale, there was a total of "x" pies

now, let's see what happened to those pies
\bf \begin{array}{lrlll}&#10;&pies\\\\&#10;&\textendash\textendash\textendash\textendash\textendash\textendash&\\&#10;&#10;Mary&x-2\\\\&#10;Kate&\cfrac{x-2}{2}\\\\&#10;\textit{pies sold}&10\\\\&#10;\textit{pies leftover}&14&#10;\end{array}

so, we had "x"
then Mary took 2, she left x - 2
Kate took half of that (x-2)/2
then 10 were sold, and 14 leftover

if we subtract all those figures, and solve for "x",
we should get what "x" was, so \bf (x-2)-\left( \cfrac{x-2}{2} \right)-10-14=0

notice, if we subtract what Mary took, and Kate, and the sold and leftover, from the original "x", we would end up with no pies :)

so.. just solve for "x"

A six-foot-tall person walks from the base of a broadcasting tower directly toward the tip of the shadow cast by the tower. When
zhuklara [117]

Answer:

270 feet

Step-by-step explanation:

For clarity, the image below represents the problem. Let's call h the height of the tower. Notice that it forms 2 triangles that are similar to side-angle-side. So, we can calculate the higher of the tower by similar triangles:

higher1/base1 = higher2/base2

h/135 = 6/3

h/135 = 2

h = 270 ft

Mrs. Barnett has 5 cups of sugar. A batch of cookies uses 1/3 cup of sugar.
MakcuM [25]

Answer:

15 batches of cookies

Step-by-step explanation:

We need to find out how many third cups do into 5 cups. We can do this by 5 ÷ 1/3

When dividing fractions, use KFC:

  • Keep the first fraction the same
  • Flip the second fraction
  • Change the sign from ÷ to ×

Therefore, 5 ÷ 1/3 = 5 × 3/1 which is 15 batches of cookies

Hope this helps!
