Total number of photos = 128

Number of photo albums = 4

Alex has 128 photos of his friend to display equally in 4 photo albums.

Equation that can be used to find number of photos in each album =

Determine which method works, substitution or elimination? 4x^2+3y^2=42x^2-6y^2=-3

GarryVolchara [31]

Given:

$\begin{gathered} 4x^2+3y^2=4 \\ \\ 2x^2-6y^2=-3 \end{gathered}$

Find the method .

Sol:

$\begin{gathered} 4x^2+3y^2=4..............(1) \\ \\ 2x^2-6y^2=-3.............(2) \end{gathered}$

2eq(1) + eq(2) then,

$8x^2+6y^2=8$

Then apply the elimination method.

$\begin{gathered} 8x^2+6y^2=8 \\ 2x^2-6y^2=-3 \\ --------- \\ 10x^2=5 \\ \\ x^2=\frac{5}{10} \\ \\ x=\sqrt{\frac{1}{2}} \end{gathered}$

A section in a stained glass window is shaped like a trapezoid. The top base is 2 centimeters and the bottom base is 4.5 centime

Elza [17]

Answer:

2.8 cm

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

$A=\frac{(B+b)h}{2}$

where

B is the length of the major base

b is the length of the minor base

h is the height of the trapezoid

In this problem, the glass window has the shape of a trapezoid. We know that:

B = 2 cm is the length of the top base

b = 4.5 cm is the length of the bottom base

$A=9.1 cm^2$ is the area of the trapezoid

Solving for h, we can find the height of the stained glass window:

$h=\frac{2A}{B+b}=\frac{2(9.1)}{2+4.5}=2.8 cm$
