How do solutions appear in the problem 3(x+1)=9

1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5

2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

Answer:

a = -29

Step-by-step explanation:

[tex]12=\frac{a+5}{-2} \\\\-24=a+5\\a=-24-5\\a=-29[/tex]

1st step is to multiply -2 on both sides

Step-by-step explanation:

12× -2 = a+5

-24 = a +5

a = 24+ 5

= 29

21/8 = 2.6

2.6 = 3 rounded

Answer: B. (-2, 18),  (0, 10),  (2, 2)

STEP 1:  f(18)= 10 - 4 * 18= 10 - 72= -62... (18, 62)

STEP 2:  f(-18)= 10 - 4 * -18= 10 - (-72)= 82... (-18, 82)

STEP 3:  f(2)= 10 - 4 * 2=10- 8= 2... (2, 2)

Explanation:4.5-8.3=-3.8 -3.8-2=5.8

Answer:

The sum of a rational number and an irrational number is irrational

Step-by-step explanation:

By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.

[tex]3+\sqrt{5} = 3+2.236067977...=5.236067977....[/tex]

Answer:    0.25 as a decimal

Answer:

0.25

Step-by-step explanation:

You can think of fractions as smaller increments of money.

2/4=0.5

3/4=0.75

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.

Imagine this happening:

1$

Uses 1/4

So... Let's look at what I've given you.

2/4=0.5

3/4=0.75

Well, let's stretch some things a liiiiitle bit.

Bob has a dollar bill blah blah...

We get to 1/4.

Le's make that 2/4.

2/4 is 0.5

So... By stretching the truth

We can infer that

If we put 1/4 back

(Oh no now the word problem creators are mad at me ;) lol)

Anyways, we can infer that by putting 1/4 back

That since 3/4 is 0.75

Then what's connected to 0.5 and 0.75?

The answer, my friend,

Is 0.25

Answer: 19

Step-by-step explanation:

1) You combine like terms with all the angles

Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93

2) You set up an equation using the formula for the sum of the interior angles

Ex. 33x + 93 = 180(n - 2)

3) Since a hexagon has 6 sides, n is 6

Ex. 33x + 93 = 180(6 - 2)

4) Solve like a regular equation

Ex. 33x + 93 = 180(6 - 2)

33x + 93 = 720

- 93 = - 93

33x = 627

- Divide 627 by 33

x = 19

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

[tex]\sigma=1150[/tex]

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

⇒      [tex]=\frac{1150}{\sqrt{500} }[/tex]

then,

⇒      [tex]=P(-1.94<Z<1.94)[/tex]

⇒      [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]

On using the table of P, we get

⇒      [tex]=0.9738 - 0.0262[/tex]

⇒      [tex]=0.9476[/tex]

Answer:

x =7

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( 2x − 3 ) = 6x + 2

Step 1: Simplify both sides of the equation.

4 ( 2x − 3 ) = 6x + 2

( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )

8x + −12 = 6x + 2

8x − 12 = 6x + 2

Step 2: Subtract 6x from both sides.

8x − 12 − 6x = 6x + 2 − 6x

2x − 12 = 2

Step 3: Add 12 to both sides.

2x − 12 + 12 = 2 + 12

2x = 14

Step 4: Divide both sides by 2.

2x  / 2  =  14  / 2

x = 7

Answer:

1. 6.75x or (6.75, 1)

2. He buys 9 sandwiches.

Step-by-step explanation:

For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x

For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.

I hope this helps :)

Answer:

The measure of the sum of interior angles of a 11-gon is [tex]1620^{o}[/tex].

Each interior angle is approximately [tex]147.273^{o}[/tex].

Step-by-step explanation:

A convex polygon has the measure of each interior angles to be less than [tex]180^{o}[/tex].

But,

sum of interior angles of polygon = (n - 2) x [tex]180^{o}[/tex]

where n is the number of sides of the polygon.

For a convex 11-gon, we have;

sum of angles of a 11-gon = (11 - 2) x [tex]180^{o}[/tex]

                                         = 9 x [tex]180^{o}[/tex]

                                         = [tex]1620^{o}[/tex]

Sum of angles of a 11-gon = [tex]1620^{o}[/tex]

To check: convex polygons' interior angles are less than [tex]180^{o}[/tex].

so that,

each interior angle of 11-gon = [tex]\frac{1620}{11}[/tex]

                                        = [tex]147.273^{o}[/tex]

Answer:

10

Step-by-step explanation:

Step-by-step explanation:

using substitution, replace y in 3x+y=-12

x=5

y=-10-17

y=-17

x=5

Answer:

-7y > 161

7y < -161

y < -23

7y > -161

y > -23

So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.
