Answer:

A number line with a closed circle on 3 and shading to the left

Step-by-step explanation:

Equation : $5(x+2)\geq (7x+2(x-1)$

$5x+10 \geq 7x+2x-2$

$12 \geq 4x$

Divide by 4 both sides

$3 \geq x$

So, $x\leq 3$

So, Therefore, the solution set is:

(-∞, 3]

So, A number line with a closed circle on 3 and shading to the left

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Let

the breadth =x

the length =6x

$\sf Area=160yard^2$

As we know that in a rectangle

${\boxed{\sf Area=lb}}$

Substitute the values

${:}\longrightarrow$ $\sf x\times 6x=160$

${:}\longrightarrow$ $\sf 6x^2=160$

${:}\longrightarrow$ $\sf x^2={\dfrac {160}{6}}$

${:}\longrightarrow$ $\sf x^2=26.6$

${:}\longrightarrow$ $\sf x=\sqrt {26.6}$

${:}\longrightarrow$ $\sf x=5.1yards$

Length=6\times 5.1=30.6yards
Breadth=5.1yards

Olin [163]

To determine the distance between two points, we use the equation,
distance = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values for the abscissa and ordinates of the points,
distance = √(0 - 2)² + (0 - 5)² = √29 ≈ 5.39
Therefore, the distance between these two points is approximately equal to 5.39.

Martha drew the following shape on her

zalisa [80]

Answer:

right angles and obtuse angles

Step-by-step explanation:

We assume that anything that <em>looks like</em> a right angle <em>is</em> a right angle.

The angles at the left end of each horizontal line are right angles.

The angles at the right end of each horizontal line are obtuse angles.

The angle where the diagonal lines meet is a right angle.

The shape contains right angles and obtuse angles.
