40 POINTS ;Find the sum of -2 and -5. Then, in two or more complete sentences, explain the steps you used to add the mixed numbers.

Answers

Answer 1

The sum of -2 and -5 is -7.

I found the sum of -2 and -5 by subtracting the two numbers. Since both numbers are negative, the equation would be set up as -2-5. This is like solving 5+2 which is 7, but just add the negative sign in front of the answer.

Answer 2

Answer:

-5 - -2 would be -3 :)

Step-by-step explanation:

Its negative because 2 is less than 5, so you cant take 5 out of it.

A worker on the production line is paid a base salary of $190 per week plus $1.19 for each unit produced. Write an equation to represent his earnings of $444.66 for a week when he produced x units. How many units did he produce? Use pencil and paper. If the worker had produced twice that number of units, what would his earnings have been? Show your work.

Answers

190 + 1.19x = 444.66
1.19x = 444.66 - 190
1.19x = 254.66
x = 254.66 / 1.19
x = 214 <== he produced 214 units

if he produced twice that number.....2 * 214 = 428
190 + 1.19(428) =
190 + 509.32 =
699.32 <=== earnings for producing twice that amount

When finding 433 - 249 using place value. What do you subtract first?

Answers

You subtract the ones place, then the tens, and lastly the hundreds place. Your answer will be 184 if you are looking for the answer as well.

Final answer:

To subtract 433 - 249 using place value, start with the units place, proceed to the tens, and then the hundreds, borrowing as needed.

Explanation:

When finding 433 - 249 using place value, you should subtract starting with the rightmost digits, which are the units, and proceed to the left towards higher place values such as tens and hundreds, if necessary. This means you subtract the ones place first (3 - 9), then the tens place (3 - 4), and finally the hundreds place (4 - 2), borrowing from the next higher place value whenever the top digit is smaller than the bottom digit.

Write a real-life problem that involves dividing a decimal by a whole number

Answers

Final answer:

A real-life problem that involves dividing a decimal by a whole number is calculating the average score of a student in a class.

Explanation:

A real-life problem that involves dividing a decimal by a whole number is calculating the average score of a student in a class. For example, if a student scores 85.4, 72.6, 90.2, and 65.3 on four tests, we can divide the sum of these scores (313.5) by the total number of tests (4) to find the average score (78.375). This demonstrates the division of a decimal (313.5) by a whole number (4) to find a real-life result.

A reasonable estimate for the height of a skyscraper is A. 1 x 10^3 feet, as it translates to 1,000 feet which is within the typical range for skyscrapers.

The reasonable estimate for the height of a skyscraper would be A. 1 x 10^3 feet. Option B is incredibly too high as no building is 1 x 10^8 feet tall. Option C and D are also incorrect as they represent very small sizes that are practically negligible and certainly not suitable for a building. A height of 1 x 10^3 feet is a reasonable approximation because it equates to 1,000 feet, which is well within the range of normal skyscrapers.

How do you estimate 92% of 104

Answers

You can round 92% to 90% and 104 to 100.

And because a percentage is out of 100, we know that 90% of 100 is 90.

92% of 104 is ~90.

If you are looking for the actual percent, then you multiply 0.92 by 104

0.92 x 104 = 97.76.

So 92% of 104 is 97.76.

Maria and Edwin have $23.00 each to spend at a book fair, where all students receive a 25% discount. They both want to purchase a copy of the same book, which normally sells for $26.50 plus 10% sales tax. To check if she has enough to purchase the book, Maria takes 25% of $26.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Edwin takes 75% of the normal purchase price and then computes 110% of the reduced price. Is Maria correct? Is Edwin correct? Do they have enough money to purchase the book? Explain your answer using complete sentences, and show your work.

Help Me
@SignoraPenguino

Answers

Answer:

Step-by-step explanation:

They are both correct, the only difference is Maria did a two step process and Edwin did a one step process the total amount it would cost is $21.87 with $1.13 left over.

The way Maria calculates the final price of the book is correct. We know that the book normally sells for $26.50 plus a 10% sales tax. We also know that the students will receive an additional 25% discount. We must understand that the sales tax is applied to the discounted price. So first we will calculate 25% of 26.50 and subtract it from that amount. So the price will then be: (26.50 - 6.625). The price is now $18.34. Then to calculate the tax, it will be (10% * 18.34), so 1.834. We add this amount to the discounted price so: (18.34+1.834) = 20.12.

The final price of the book is $20.12 and Maria can get it and still save a little money.

Mario took clothes to the cleaners three times last month. first, he brought 3 shorts and 1pair of slacks and $10.96. then, he brought 7 shirts, 2 pairs of slacks, and a sports coat and paid $30.40. finally, he brought 4 shirts and 1 sports coat and paid$14.45. How much was he charged for each shirt, each pair of slacks, and each sports coat.

Answers

Final answer:

Each shirt costs approximately $0.66, each pair of slacks costs approximately $8.97, and each sports coat costs approximately $11.80.

Explanation:

To find the cost of each item, we need to solve a system of equations. Let x be the cost of each shirt, y be the cost of each pair of slacks, and z be the cost of each sports coat. From the given information, we can set up the following equations:

3x + y = 10.96

7x + 2y + z = 30.40

4x + z = 14.45

Now, we can solve the system of equations using any method of our choice. Let's use the method of substitution:

From equation 1, we can solve for y: y = 10.96 - 3x.

Substituting this value of y into equation 2, we get: 7x + 2(10.96 - 3x) + z = 30.40.

Simplifying and rearranging this equation gives us: -5x + z = 8.48.

Now, we can solve for z in terms of x from equation 3: z = 14.45 - 4x.

Substituting this value of z into the equation we obtained earlier, we get: -5x + (14.45 - 4x) = 8.48.

Simplifying and rearranging this equation gives us: -9x + 14.45 = 8.48.

Now, we can solve for x:

-9x = 8.48 - 14.45

-9x = -5.97

x = -5.97 / -9

x = 0.6633

Therefore, each shirt costs approximately $0.66.

Now that we know the value of x, we can substitute it back into equation 3 to find the cost of each sports coat:

z = 14.45 - 4(0.6633)

z = 14.45 - 2.6532

z = 11.7968

Therefore, each sports coat costs approximately $11.80.

Finally, we can substitute the values of x and z into equation 1 to find the cost of each pair of slacks:

3(0.6633) + y = 10.96

1.99 + y = 10.96

y = 10.96 - 1.99

y = 8.97

Therefore, each pair of slacks costs approximately $8.97.

What is the distributive property of 48 + 72?

Answers

Answer:

12(4+6)

Explanation:

To write a problem using the distributive property, we must find a factor they have in common.

48 and 72 are both divisible by 12; this means that we can "pull out" 12. This will be what we multiply by in the distributive property.

48/12 = 4 and 72/12 = 6; this means this is what goes inside parentheses. This gives us

12(4+6)

The distributive property is expressed as 24 (2 + 3) = 24(2) + 24(3)

The distributive property is a property of multiplication used in addition and subtraction. In our case it is used in addition.

The property can be express mathematically as follows.

a(b + c) = ab + ac

Therefore,

lets find the factor of 48 and 72 to represent the distributive property.

24 (2 + 3) = 24(2) + 24(3)
