Answer:

1800 bricks

Step-by-step explanation:

Given

Sidewalk = 100ft by 4ft

Brick = 8 inches by 4 inches

Required

Determine the minimum number of bricks

First, we need to determine the area of both;

Sidewalk = 100ft * 4ft

Sidewalk = 400ft^2

Brick = 8in * 4in

Brick = 32in^2

Number of bricks is calculated as follows;

Number = \frac{Sidewalk}{Brick}

Number = \frac{400ft^2}{32in^2}

Convert ft^2 to in^2

Number = \frac{400 * 144in^2}{32in^2}

Number = \frac{57600in^2}{32in^2}

Number = 1800

W = 3x + 7y solve for y
mario62 [17]

Answer:

The value of the equation y=\frac{W-3x}{7}.

Step-by-step explanation:

Consider the provided equation.

W = 3x + 7y

We need to solve the provided equation for y.

Subtract 3x from both side.

W-3x= 3x-3x+ 7y

W-3x=7y

Divide both sides by 7.

\frac{7y}{7}=\frac{W-3x}{7}

y=\frac{W-3x}{7}

Hence, the value of the equation is y=\frac{W-3x}{7}.
