Compare partial products and regrouping

Mathematics
1 answer:
Stella [2.4K]3 years ago
5 0

Let us first describe how partial product and regrouping are alike:

Partial Products and Regrouping are alike because both methods are multiplied by one number and if the product of the number has 2 digits it can be carried.

Now let us discuss how they are different:

Partial Products and Regrouping are different because Partial Products are doing multiplication step by step and regrouping is regular multiplication.

Hope it helps.

I am thinking of a number. When I double my number and then subtract the result from five, I get negative one. What is my number
pogonyaev

Answer:

3

Step-by-step explanation:

To turn the word problem into an equation, when we read:

"I am thinking of a number" we write "x"

"when I double my number" we write "2x"

"and then subtract the result from 5" we write "5 - 2x"

"I get negative one" we write "-1 = 5 - 2x"

Now we solve for the number, which is x.

<em>Equation: </em>-1 = 5 - 2x

-1 = 5 - 2x

subtract 5 from both sides

-6 = -2x

divide both sides by -2

3 = x

<h3>There we go! The number is </h3><h2>3</h2>

Please help ;-; <br> Solve for the simultaneous equation….<br> 5x+y=17<br> X+y=3
Svetach [21]

<u>Given Equation</u>:-

  • 5x+y=17 . . . . . . . . 1
  • x+y=3 . . . . . . . . . . 2

<u>To find</u> :

  • value of x
  • value of y

<u>Solution</u> :

<u>Let's start with equation 2</u>:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

  • 5x+y=17
  • 5x + (3 - x) = 17
  • 5x - x + 3 = 17
  • 4x + 3 = 17
  • 4x = 17 - 3
  • 4x = 14
  • x = 14/4
  • x = 7/2
  • x = <em>3.5</em>

<u>Now Let's find value of y</u><u>:</u>

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = <em>0.5</em>
