Answer: The mathematical statement is given as

"2.5 greater than the product of -0.5 and a number"

Product means times

So, we have the following representation

"2.5 greater than the product of -0.5 and a number" ⇒  2.5 greater than -0.5 * a number

Let the number be x

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒  2.5 greater than -0.5x

Greater than is represented by >

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒  2.5 > -0.5x

Next, we plot the graph of the inequality expression

Answer OPTION B

Step-by-step explanation:

Answer:

Step-by-step explanation:

This problem is asking you to substitute for x.

1. 38.1 + x when x=-6.1

It is giving you what the value of x is, -6.1.

Substitute

38.1 - 6.1

=32

When ever it says x =

That number replaces x and then you solve.

2. 18.7 + x      x = 8.5

18.7 + 8.5

27.2

Do this for the rest of the problems.

Answer: Remove, Multiply, Add (RMA)

Step-by-step explanation:

I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Answer:

Step-by-step explanation:

Substitute 8 for x

3(8) - 1

Solve:

3 x 8 = 24

24 - 1 = 23

Next, substitute for x in the inequality with the answer you just made. See if it's true.

23 [tex]\leq[/tex] 2

The inequality is NOT TRUE

Same thing for the next one

1/2(8) + 5

Solve:

1/2 x 8 = 4

4 + 5 = 9

Substitute for x in the inequality with the answer you just made. See if it's true.

9 > 2

This inequality is TRUE

Answer:

x = - 26

Step-by-step explanation:

2x - 11 - 3x = 15

- x - 11 = 15

- x = 15 + 11

- x = 26

x = - 26

Answer: x = -26

Step-by-step explanation:

How to solve your problem

2x-11-3x=15

Solve

1

Combine like terms

2x - 11 3x +15

-x -11 = 15

Add

11

to both sides

-x-11=15

-x-11+11 = 15 + 11

Answer:

0.42+ 0.17w); 1.10$

It would cost us $1.10 to send a 4-ounce letter.

Answer:

C) 0.42 + 0.17 | w: $1.10

Step-by-step explanation:

Note that amount of ounces is denoted by the variable "w". The cost per ounce is $0.17, while the constant charge (charge doesn't change per ounce) is $0.42.

Set the equation:

(Cost per ounce x Amount of ounces) + Constant charge = Total charge:

(0.17x) + 0.42 = Total Charge

Total Charge = 0.17x + 0.42

Next, you are solving for the cost of 4 ounces. Plug in 4 in the variable, x.

Total Charge = 0.17x + 0.42

                      Plug in 4 for x.

                      = 0.17(4) + 0.42

                      Follow PEMDAS, First, multiply, then add:

                      = (0.17 * 4) + 0.42

                      = 0.68 + 0.42

                      = 1.10

~

C) 0.42 + 0.17  | w: $1.10 is your answer.

Answer:

Step-by-step explanation:

Even though death valley is at -282 feet in relation to sea level, it's 282 feet away in distance. So even though the distance is in a different/negative direction, it's still an ACTUAL distance, and we call that absolute value.

the letter "w" represents a variable, and the letter "h" also represents a variable. The goal is to solve for either "w" or "h" by using the given information and the rules of algebra.

To solve this equation, we can start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:

w-4/h-4=4/3

3(w-4/h-4)=3(4/3)

This simplifies to:

3w-12/3h-12=4

Next, we can simplify the expression on the left side of the equation by combining like terms:

3w-12/3h-12=4

3w-3h=-8

Finally, we can solve for either "w" or "h" by using the given information and the rules of algebra. For example, we can solve for "w" by adding 3h to both sides of the equation:

3w-3h=-8

3w=-8+3h

w=-2+h

This means that the value of "w" is equal to the value of "h" minus 2. Alternatively, we could solve for "h" by adding 3w to both sides of the equation:

3w-3h=-8

-3h=-8+3w

h=2-w/3

This means that the value of "h" is equal to 2 minus the value of "w" divided by 3.

Answer:

-17

Step-by-step explanation:

I will represent the question mark with the variable [tex]x[/tex].

[tex]x - 11 + 12 = -16[/tex]

To solve for [tex]x[/tex], we need to isolate it.

To do this, subtract 12 from both sides.

[tex]x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28[/tex]

Then, add 11 to both sides.

[tex]x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17[/tex]

[tex]x = -17[/tex]

So, the integer that makes the equation true is -17.
