Answer:

Step-by-step explanation:

(5y - 2.3) + (-2y - 4.3) = 3y - n              Remove the brackets

5y - 2.3 - 2y - 4.3 = 3y - n                    Combine like terms

3y - 6.6 = 3y - n                                    Subtract 3y from both sidess

- 6.6 =  - n                                             Divide by - 1

6.6 = n

Use the zero property product to find the solutions to the equation x^2-9= 16
Luba_88 [7]
Subtract 16 to get
  x^2 -25 = 0
Factor this as
  (x -5)(x +5) = 0

The zero product property tells you the product will be zero when one of the factors is zero.

For x-5 = 0
  x = 5

For x+5 = 0
  x = -5

The appropriate choice is
  3) x=-5 or x=5

Simplify the expression. <br> 1/2r – 2r + 6 – 3
Hoochie [10]

Answer:

-3(r-2)/2

Step-by-step explanation:

r/ 2 − 2 r + 6 − 3

r /2 − 2 r⋅ 2/ 2+ 6 − 3

r/ 2 + − 2r ⋅ 2/ 2 + 6 − 3

r − 2 r ⋅ 2 /2 + 6 ⋅ 2/ 2 + − 3 ⋅ 2/ 2

r − 2 r ⋅2 + 6⋅ 2 − 3 ⋅ 2 /2

r − 4 r + 12 − 6 /2

−3 ( r − 2 ) /2

Hope that helps! Plz, mark brainiest! :D

Have a great day!
