Answer:

50 cents The red on the right end.

Step-by-step explanation:

Let the chocolate chip cookies = x

Let the jumbo popcorn = y

Julie

y + 2x = 5

Marvin

y + 4x = 6 Subtract

-2x = - 1 The y's disappear. You are left with 1 dollar (negative). Divide by - 2

-2x/-2 = - 1 / -2

x = 1/2

x = 0.5 or 50c

Each cookie costs 50c

Find the volume of a pyramid with a square base, where the perimeter of the base is 8.2\text{ cm}8.2 cm and the height of the py

7nadin3 [17]

Answer:

$V=18.2cm^3$

Step-by-step explanation:

The volume of the pyramid is given by:

$V=\frac{A_{b}h}{3}$

where $A_{b}$ is the area of the base and $h$ is the height.

We know that the height is:

$h=13cm$

Thus we need to find the area of the square at the base.

The perimeter of the square is:

$p=8.2cm$

this means that the length of the sides of the square is :

$l=\frac{p}{4}\\ \\l=\frac{8.2cm}{4}\\ \\l=2.05cm$

Now we can find the area of the base which the area of the square:

$A_{b}=l^2\\A_b=(2.05cm)^2\\A_b=4.2025cm^2$

and finally we find the volume:

$V=\frac{A_{b}h}{3}$

$V=\frac{(4.2025cm^2)(13cm)}{3}\\ \\V=\frac{54.6325cm^3}{3}\\ \\V=18.2108cm^3$

Which rounded to the nearest tenth of a cubic centimeter is: $V=18.2cm^3$

X2 = 14 − 3x is my question

vladimir1956 [14]

X=14/5 if you want solution here:
Use the commutative property to reorder the terms: 2x=14-3x
Move the variable to the left - hand side and change sign: 2x+3x=14
Collect like terms: 5x=14
Divide both sides of the equation by 5: x=14/5
