At the family reunion there were 15 more family members there this year than at the last family reunion. There were 46 people at
Kipish [7]
The equation would be x+15=46. I came up with this equation because we are given the total number of people at the reunion this year and we know how many more people are here this year than last year. The unknown is the number of people last year. That is why x would represent the number of people at the reunion last year because that is the unknown. If we add 15 to the number of people last year, it will give us 46( the number of people at the reunion this year).
To find x, we just use opposite operation to get the answer. Opposite of addition is subtraction so, we subtract the number of more people and the reunion this year from the total number of people at the reunion to get the unknown number of people at the reunion last year. 46-15 is 31. Therefore we know that 31 people were at the reunion last year

The formula for the area of a triangle is 1/2bh=A. Which of the following is not a possible first step to rearrange this formula

A: Multiply by 12

The 1/2 is already multiplied by the bh, so in order to "undo" that multiplication, you have to do the opposite, which is to divide.

1. Consider the following system of linear equations.
timurjin [86]

Using the multiplication property, we have the following equivalent system of linear equations:

  • 4/9x + 4/3y = 20/12  
  • 2/3x - 4/3y = 5/3

<h3>What is an Equivalent System of Linear Equations?</h3>
  • Systems that are equivalent will have the same solution.
  • Creating equivalent system helps us to find the variables in a system of equations.

Given:

1/3x + y = 5/4 ---> Equation 1

2/3x - 4/3y = 5/3 ---> Equation 2

To create an equivalent system, multiply equation 1 by 4/3, and multiply equation 2 by 1.

Thus, using the multiplication property, we have the following equivalent system of linear equations:

  • 4/9x + 4/3y = 20/12  
  • 2/3x - 4/3y = 5/3
