The quotient k and 22 is −66.

Answers

Answer: k=−1,452

Step-by-step explanation:

k/22 x 22 = −66 x22

Final answer:

The value of 'k' can be determined by isolating 'k' in the equation. This results in k = 22 * -66, simplifying to k = -1452.

Explanation:

The equation conveyed in the question can be written as k/22 = -66. To find the variable k's value, we need to isolate k in the equation. This can be done by keeping the inverse operation on both sides of the equation balanced. Since k is currently divided by 22, we must multiply both sides of the equation by 22 to get k independently.

When we do this, the equation becomes k = 22 * -66. Then, solve for k by multiplying 22 and -66 together. So, kequals -1452.

Show how to multiply 46.93×1.8

Answers

To start off this is multiplication and not addition nor subtraction where you have to line up your numbers like 46.93+ 1.98No, instead you put them in any order such as46.93x. 1.98---------------37544421370+ 469300------------------92.9214 ------> This is your answer!1)Multiply the 3 in 46.93 to the 8 in 1.98 which is 24. 2) Then you multiply the 9 in 46.93 to the 8 in 1.98 which gives you 72 and don't forget to add the 2 from 24. You get 74. 4)You then multiply the 6 in 46.93 to the 8 in 1.98 and you get 48, add the 7 from 74, and you get 55. 5) You multiply the 4 in 46.93 to the 8 in 1.98 and you get 32, plus the 5 from 55 and you get 37. Your first answer should be 37544.6) After you get this answer, you add a zero underneath the 4 in the one's place from your previous answer. 7) This step might be a little hard to remember, but you do the same procedure as you were doing in steps 1-6. This time on the other hand, you multiply each value in 46.93 to the 9 in1.98. 8)After completing those exact steps, your secondary answer should be 421370. 9) Once having this answer, you multiply 46.93 to the 1 in 1.98 and your third answer should be 469300. 10) The next step is to add up all three of your answers together and you get the final answer. You should be getting 929214. 11) The last and final step is to count the spaces of decimals your multiples' have which are 4, and you move 4 spaces to the left and you get 92.9214.

Final answer:

To multiply 46.93 and 1.8, you treat 1.8 as 18, perform the multiplication, and then reinsert the decimal in the right spot. After carrying out these steps, you'll arrive at the result of 84.474.

Explanation:

To multiply the numbers 46.93 and 1.8, you can use the standard multiplication algorithm. Start by thinking of 1.8 as 18, but remember to put the decimal back in the result. Here are the steps:

  1. Multiply 18 by 3 (the number in the hundredths place of 46.93). The result is 54. Write down 54.
  2. Multiply 18 by 9 (the number in the tenths place of 46.93) and add the carried over 5 from the last step. The result is 167. Write down 167, but shift it one place to the left.
  3. Multiply 18 by 6 (the number in the ones place of 46.93). Write this down, shifted two places to the left.
  4. Multiply 18 by 4 (the number in the tens place of 46.93). Write this down, shifted three places to the left.
  5. Add up all the lines. The result should be 84474.
  6. Count how many decimal places are in the numbers you are multiplying. In this case there are two (46.93 has two, 1.8 has one). So put a decimal in your result two places from the right. The final answer is 84.474

How can I adjust a quotient to solve a division problem

Answers

for example you have five times twevle people so that's 60people. 5 times 12 is 60 and 12 times 5 is 60 so 60 dividedby 5 is 12 and 60 divided 12 is five. that's what division can be like

Final answer:

To adjust a quotient in a division problem, you can multiply both the dividend and divisor by the same number.

Explanation:

To adjust a quotient in order to solve a division problem, you can multiply both the dividend and divisor by the same number. This will not change the value of the quotient, but it will make the division easier to solve.

For example, if you have 12 ÷ 3 and you want to adjust the quotient, you can multiply both 12 and 3 by 10 to get 120 ÷ 30. The quotient remains the same, but now you can easily divide 120 by 30 to get the answer, which is 4.

In summary, adjusting a quotient involves multiplying both the dividend and divisor by the same number to simplify the division problem.
