Find the number of bricks to be laid in a square path of side 18cm if the side of each square bricks is 3cm

AlladinOne [14]

Answer:

36 bricks

Step-by-step explanation:

We are given;

Length of the square path as 18 cm
Length of the square brick as 3 cm

We are required to determine the number of bricks that would be laid on the square path.

Number of bricks = Area of the path ÷ area of one brick

Area of a square = l²

Therefore;

Area of the square path = (18 cm)²

= 324 cm²

Area of square brick = (3 cm)²

= 9 cm²

Therefore;

Number of bricks = 324 cm² ÷ 9 cm²

= 36 bricks

Can someone help me with one pleaseT (ToT)

uysha [10]

Answer:

Add 1 to both sides.

Multiply both sides by -2.

Add 8 to both sides.

Divide both sides by 5.

Step-by-step explanation:

<u>Step 1</u>

$-\dfrac{1}{2}(5x-8)-1=6\quad \quad \textsf{Write the equation.}$

<u>Step 2</u>

$-\dfrac{1}{2}(5x-8)=7 \quad \quad \textsf{Add 1 to both sides.}$

This is called the <u>Addition Property of Equality</u>. When the same number is added to both sides of an equation, the two sides remain equal.

$\implies -\dfrac{1}{2}(5x-8)-1+1=6+1$

$\implies -\dfrac{1}{2}(5x-8)=7$

<u>Step 3</u>

$5x-8=-14 \quad \quad \textsf{Multiply both sides by -2.}$

This is called the <u>Multiplication Property of Equality</u>. When both sides of an equation are multiplied by the same number, the two sides remain equal.

$\implies -2 \cdot -\dfrac{1}{2}(5x-8)=-2 \cdot 7$

$\implies 5x-8=-14$

<u>Step 4</u>

$5x=-6 \quad \quad \textsf{Add 8 to both sides.}$

This is called the <u>Addition Property of Equality</u>. When the same number is added to both sides of an equation, the two sides remain equal.

$\implies 5x-8+8=-14+8$

$\implies 5x=-6$

<u>Step 5</u>

$x=-\dfrac{6}{5} \quad \quad \textsf{Divide both sides by 5.}$

This is called the <u>Division Property of Equality</u>. When both sides of an equation are divided by the same number, the two sides remain equal.

$\implies \dfrac{5x}{5}=\dfrac{-6}{5}$

$\implies x=\dfrac{-6}{5}$

<u>Conclusion</u>

<u></u>

<u /> $\begin{aligned}-\dfrac{1}{2}(5x-8)-1 & =6 & \quad \quad& \textsf{Write the equation.}\\\\-\dfrac{1}{2}(5x-8) & =7 & & \boxed{\textsf{Add 1 to both sides.}}\\\\5x-8 & =-14 & & \boxed{\textsf{Multiply both sides by -2.}}\\\\5x & =-6 & & \boxed{\textsf{Add 8 to both sides.}}\\\\x & =-\dfrac{6}{5} & & \boxed{\textsf{Divide both sides by 5.}}\\\end{aligned}$
