The camp cook has 6 dozen eggs. He uses 18 eggs to bake some brownies. Then he uses twice as many eggs to make pancakes. How many eggs does the cook have left? Use reasoning to write and evaluate an expression that represents the problem.

18 eggs

Step-by-step explanation:

The camp cook has 6 dozen eggs:

A dozen of egg = 12 pieces of eggs.

6 dozen of eggs

= 6*12

=72 eggs.

He uses 18 eggs to bake some brownies.

He uses twice as many eggs (he used for brownies ) to make pancakes.

= 2 * 18

= 36 eggs

To know the number of eggs the cook have left, we will subtract all the number of eggs he used, from the total crates he has.

Total eggs

= 6 dozens

= 6*12

= 72 eggs

Number of eggs used:

For brownies:

= 18 eggs

For pancakes: Twice brownies

= 2 * 18

= 36 eggs

Sum of used eggs = 18 + 36

= 54 eggs

Number of Eggs the cook have left:

= Total eggs - Used eggs

= 72 eggs - 54 eggs

=18 Eggs

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'.
