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

Answers
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

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; $2.36
0.42 + 0.17 w; $1.10
0.42 + 0.17 w; $2.36
Answers
Answer:
0.42+ 0.17w); 1.10$
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.

For question 2/3 ÷ 1/4
Answer: 8/3 or 2 2/3
Step-by-step explanation:
Common denominator is 12
8/12 ÷ 3/12
Divide (Multiply by the reciprocal)
8/12 x 12/3
Answer is 8/3 or 2 2/3
4a: to divide fractions, you keep change flip. keep the 2/3, change the dividing sign to a multiplication sign, and flip 1/4 to 4/1. then multiply. 2 • 4 is 8, and 3 • 1 is 3. 8/3 is an improper fraction, since 8 is greater than 3. 8 can go into three 2 times, which is 6, and leaves 2 behind, making the answer 2 and 2/3.
4b: do the same process as 4a, keep change flip. keep 10/3, change the division to multiply, and flip 2/6 to 6/2. for this one, you can cross multiply. for example, across from 10 is 2. 2<10, so you would see how many times 2 can go into 10, which is 5 times. 2 can only go into 2 one time, so you change the two to a one. do the same thing with 6 and 3. 3<6, so 3 can go into 6 two times, so the six would turn into a 2. 3 can go into 3 one time, so change the 3 to a 1. multiply the new numbers. 5 x 2 is 10, and 1 x 1 is 1. your answer is 10/1 which can also be 10. answer is 10.
4c: same process. keep change flip. end up with 5/6 times 12/7. you can only cross multiply with 6 and 12, since 5 and 7 don’t have a common factor. so for 6 and 12, 6<12. 6 goes into 12 2 times so the 12 turns into a 2. 6 goes into 6 only once, so it turns into a one. multiply. 5 x 2 is 10, 1 x 7 is 7. 10/7 is an improper fraction, so u have to change it. 10 goes into 7 once and three is left. so the answer is 1 and 3/7.
4d: same process keep change flip. we have to change 2 and 3/4 into an improper fraction so it can be easier to multiply. 2 x 4 is 8, and 8 + 3 is 11, so it would be 11/4. keep 11/4, switch division to multiplication, and flip 4/3 to 3/4. multiply and get 33/16. 33/16 is improper so u have to change it. 33 goes into 16 twice and one is left. answer would be 2 and 1/16

w-4/h-4=4/3 can someone please answer this its for homework someone told me it was 8 but i got 12
Answers
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.
