Rs = 8y + 4 , ST = 4y + 8 , and RT = 36 , find the value of y
Natasha_Volkova [10]
I assume that you meant RS and ST are segments of RT.  If that is true then:

RS+ST=RT, using the values for these given...

8y+4+4y+8=36  combine like terms on left side

12y+12=36  subtract 12 from both sides

12y=24  divide both sides by 12

y=2

7.5d = 2.5d Lin divided each side by 2.5d and Elena subtracted 2.5d from each side with both leads to the solution
dedylja [7]

Answer:

Elena's move will lead to the solution of the problem

Step-by-step explanation:

To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning

Given:

7.5d = 2.5d

Lin divides each side by 2.5d, Lin:

7.5d / 2.5d = 2.5d / 2.5d

3 = 1

This can not be the solution to the problem because 3 can not be Equal to 1

Elena subtracts 2.5d from each side

7.5d = 2.5d

7.5d - 2.5d = 2.5d - 2.5d

5d = 0

This can lead to the solution of the problem

Elena's move will lead to the solution of the problem
