Answers

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

Do this for the rest of the problems.

Help!!!! the integer that makes the following addition sentence true.

? + (-11) + 12 + =-16

Answers

-17

As you can see the end result will end up with -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.

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

okay i’ll try to explain it the best i can.

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

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

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

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

x = - 26

Answer: x = -26

Step-by-step explanation:

How to solve your problem

2x-11-3x=15

Solve

Combine like terms

2x - 11 3x +15

-x -11 = 15

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

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.
