Answer 1

Answer:

[tex]x\geq -4[/tex]

Step-by-step explanation:

[tex]3x-9\geq-21[/tex]

add 9 to both sides

[tex]3x-9+9\geq -21+9[/tex]

[tex]3x\geq -12[/tex]

divide both sides by 3  

[tex]\frac{3}{3}x \geq \frac{-12}{3}[/tex]

[tex]x\geq -4[/tex]

Plot a solid dot on -4 on the number line because the inequality sign is great than or equal to and x the great than or equal to -4.

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place

please don't answer if you are wrong

Answers

Answer:

38.3

Step-by-step explanation:

The perimeter of the figure can be broken down into the perimeter of 3 sides of the parallelogram, and the perimeter of the semicircle (without its diameter).

The three sides of the parallelogram would be 14+14+4=32.

The perimeter of the semicircle would be 1/2*diameter*pi, which is about 1/2*4*3.14=6.28.

Therefore, the perimeter is 32+6.28=38.3 (to the nearest tenths).

Answers

$180/36=5
so we know 1 pound=5 dollars
10/5=2
so your answer would be
*2 pounds*

Answer:

20 lbs cost $10

Step-by-step explanation:

36 lbs= $180

x        = $10

Let's use the cross method

36*10 = 180x

360 = 180x

360/180 = 180x/180

20= x

20 lbs cost $10

£880 is divided between Pip, Sara & Gordon so that Pip gets twice as much as Sara, and Sara gets three times as much as Gordon. How much does Sara get?
I don’t know how to work this out

Answers

Answer:

Assume Gordon got X dollar

Then

sara got = 3*x= 3x

Pip got = 2*3x= 6x

Now,

x + 3x + 6x = 880

10x =880

x= 88

Sara got = 3x = 3*88 = 264

Slope: -5/1

Step-by-step explanation:

The slope is always the coefficient of x in y=mx+b, so m is -5 (you don't reverse it)

Answer: A) m = -5/1

Step-by-step explanation: The format of slope intercept form is y=mx+b , therefore M= -5/1.

Here is a five-sided polygon. Show how you could use area-reasoning strategies—decomposing, rearranging, enclosing with a shape, etc.—to find the area of the polygon. (You only need to describe or show how the area could be found; it is not necessary to actually calculate the area.)

Answers

Answer:

i can explain it to you if u want

Step-by-step explanation:

Divide the polygon into 5 triangles by using each side as a base and joining the vertices of the polygon to a common point (for example, the centre). If the polygon is regular the angle at the vertex of each triangle is 360/5=72 degrees, so you have 5 isosceles triangles of equal area. Find the area of one and multiply by 5 to get the total area.multiply 5 times the lenght of oneside
