Help a girl out! Plz hurry! Make sure to put answer as decimal!

Answer:

the answer is b

Step-by-step explanation:

The possible inequality for x is 4 < x < 20.

The correct option is (B).

Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides.

We are given that,

A triangle has sides measuring 8 inches and 12 inches. If x represents the length in inches of the third side

8+12=20

so it has to be less than 20, and 12-8=4,

So it has to be more than 4,

So the only answer that makes sense is

4<x<20.

Therefore, option B is correct.

Answer:

- [tex]\frac{15}{4}[/tex]

Step-by-step explanation:

Given

3x - 8y = 39 ← substitute x = 3 into the equation

3(3) - 8y = 39

9 - 8y = 39 ( subtract 9 from both sides )

- 8y = 30 ( divide both sides by - 8 )

y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

It is correct trust me.

Answer:

It is a rhombus.

Step-by-step explanation:

We have the four equations:

3x - y = -4

3y - x = 4

3y = x + 12

y = 3*x - 4

First, we need to write all of them in slope-intercept form, so they are easier to read.

We get:

y = 3*x+ 4

y =  (1/3)*x + 4/3

y = (1/3)*x + 12/3

y = 3*x - 4

First, we can see that:

y = 3*x+ 4 and y = 3*x - 4

are parallel lines, because they have the same slope.

y =  (1/3)*x + 4/3 and y = (1/3)*x + 12/3  also are parallel lines, because they have the same slope.

Then this is a parallelogram.

Now, here we have two slopes, 3 and 1/3.

Remember that for a line y = a*x + b

A perpendicular line would be written as:

y = -(1/a)*x + c

From this we can see that there are no perpendicular lines in our set of lines.

Then this can not be a square nor a rectangle.

It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.

Then this can only be a rhombus.

Below you can see the graph of the four lines to see which quadrilateral they form.

Answer:

X < 4

Step-by-step explanation:

-7 > 13 - 5X

-7 = 13 - 5X

-7 -13 = -5X

-20 = -5X

-20 /-5 = -5X /-5

4 = X

4 > X

X < 4

Step-by-step explanation:

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

Answer:

13cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 12cm

b = 5cm

c = hypotenuse

[tex]12^{2} +5^{2} =c^{2}[/tex]

[tex]144+25=c^{2}[/tex]

[tex]\sqrt{169} =c[/tex]

13 = c

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169

square root of 169=13

13=c

Answer:

1/3(x-10)=-4

We move all terms to the left:

1/3(x-10)-(-4)=0

Domain of the equation: 3(x-10)!=0

We add all the numbers together, and all the variables

1/3(x-10)+4=0

We multiply all the terms by the denominator

4*3(x-10)+1=0

Wy multiply elements

12x(x+1=0

Answer:

0.6b - 3c

Step-by-step explanation:

Multiply 0.2 and 3b

0.2 x 3b = 0.6b

Then multiply 0.2 and 15c

0.2 x 15c = 3c

We can't add these, 3c and 6b because they have different letters.

different letter vs. different letter =

don't add

different letter vs. normal number like 5 =

dont add

same letter vs. same letter =

add

normal number vs. normal number =

add

This all goes the same for dividing, subtracting, and multiplying
