Can someone help me with this question (Geometry) can you also explain!

Answer:

Yes, it's a rational number

Step-by-step explanation:

-3/7. It is a rational because. It can be written as p/q form. Where p/q are non zero number. And in decimal it would be -0.42

Answer:

-3/7 is a rational because as it can be written as p/q form where p/q are integers and q≠0.

-3/7 = -0.4285

To the nearest hundredth,

=> -0.43

Answer:  (1.125,-0.25)

Step-by-step explanation:  The point that is the same for both equations is the point where they intersect.  It appears from the graph to be around (1,0).  We should confirm this by deriving the equation for each line and then solving them.  Use the standard format:  y = mx+b, where m is the slope and b the y-intercept.

I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x).  The y intercept is 2 (b).  This equation would be y = mx+b, or y = -2x + 2.

The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1

Set these two equations equal to each other and solve for x.

-2x+2=(2/3)x-1

x = 1.125

Use that value of x to solve for y:  y = -0.25

The point of intersection is therefore (1.125, -0.25)

Step-by-step explanation:

-5 4/11 = -59/4 , this is a fraction and all the fractions are rational numbers

√31 is not rational number

7.608 = 7608/10000, this is a rational number

18.466666... = 277/15, this is a rational number

The number, option (B) √31 is not a rational number.

A rational number can be defined as any number which can be represented in the form of p/q where q ≠ 0. It can be made by dividing an integer by an integer.

For the given situation,

The number is a rational number when it is in the form of fraction as [tex]\frac{p}{q}[/tex].

The options are

a) -5 4/11

⇒ [tex]-5\frac{4}{11}=-\frac{59}{11}[/tex]

The number is expressed in fraction. So it is a rational number.

b) √31

The number cannot be expressed in fraction. So it is not a rational number.

c) 7.608

⇒ [tex]7.608=\frac{7608}{1000}[/tex]

The number is expressed in fraction. So it is a rational number.

d) 18.46 repeating

⇒ [tex]18.4666666667=\frac{277}{15}[/tex]

The number is expressed in fraction. So it is a rational number.

Hence we can conclude that the number, option (B) √31 is not a rational number.

12. 35, 45,55,65,75,85,95

Step-by-step explanation:

10 dollars per week for 7 weeks in equivalent to 10x7 which equals $70.

If you already had $25 you would do 10x7+25. Using PEMDAS you would multiply first (10x7=70) then add 25 (70+25=95)

Answer:

Step-by-step explanation:

sorry if its wrong

Answer:

B

Step-by-step explanation:

x and 83 are same- side interior angles and sum to 180° , then

x + 83° = 180° ( subtract 83° from both sides )

x = 97° → B

Answer:

The middle integer is 11.

Step-by-step explanation:

Hi there!

Let x be the smallest of the three consecutive integers.

Let x+1 and x+2 be the next consecutive integers. This makes x+1 the middle integer.

We're given that the third integer subtracted from the sum of the first two integers equals 9. We can use this to construct an equation:

[tex](x)+(x+1)-(x+2)=9[/tex]

Combine like terms:

[tex]x+x+1-x-2=9\\x+x-x+1-2=9\\x-1=9\\x=10[/tex]

Therefore, the smallest integer is 10.

Because the middle integer is x+1, the middle integer is 11.

Answer and Step-by-step explanation:

To solve for x, you need to get it by itself.

First, add 6 to both sides, and 3x to both sides of the equation.

4x = 28

Now divide by 4 on each side.

x = 7

x = 7 will be your answer.

Answer:

x=25

Step-by-step explanation:

so -3x+22 is 19x

I know this because since it's a negative number adding a larger number will make it a positive number

now what we have to do is to add 19x+6 and that's 25x or just x

Answer:

9

Step-by-step explanation:

set up the equation: ab+bc=ac

(x-6) + 7 = (-8+2x)

Step 1: Simplify both sides of the equation.

x−6+7=−8+2x

x+−6+7=−8+2x

(x)+(−6+7)=2x−8(Combine Like Terms)

x+1=2x−8

x+1=2x−8

Step 2: Subtract 2x from both sides.

x+1−2x=2x−8−2x

−x+1=−8

Step 3: Subtract 1 from both sides.

−x+1−1=−8−1

−x=−9

Step 4: Divide both sides by -1.

−x/−1  =  −9 /−1

x=9
