Explain how to use a pattern to find the product of a decimal
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

Help!!!! the integer that makes the following addition sentence true.
? + (-11) + 12 + =-16
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.

Consider the function below. Find f(8)
Answer: The First one isn't valid
The second one is equal to 9
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
Hope this helps!!!

The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. Write an expression to represent the cost for mailing a letter that is w ounces. Then find the cost for mailing a letter that is four ounces.
0.17 + 0.42 w; $1.85
0.17 + 0.42 w; $2.36
0.42 + 0.17 w; $1.10
0.42 + 0.17 w; $2.36
Answer:
0.42+ 0.17w); 1.10$
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:
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

Logan is 5 feet tall and his shadow is 8 feet long. At the same time of day, a tree’s shadow is 32 feet long. What is the height of the tree?
29 feet
51 feet
20 feet
24 feet
Answer: 29 ft because if his shadow is 8 ft that tells me that the equation would be less and and 8-5=3 so 32-29=3

Which graph represents the inequality 2.5 is less than the product of −0.5 and a number?
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

5. 21.6+ x for x=-11.2
6. 8/13+x for x=2/13
please help me this is due today
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.
