Answer:
12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y ) = 21.51.
Step-by-step explanation:
Here, the given expression is:
12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y )
Now, we need to evaluate the given expression for y = 3
12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y ) by the rule of BODMAS
12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y ) = 12 - 3(3) ÷ 2 + 3(2(3) -4 ÷ 3)
= 12 - 9 ÷ 2 + 3( 6 - 4 ÷ 3)
= 12 - 9 ÷ 2 + 3( 6 - 4 ÷ 3)
= 12 - 4.5 + 3( 6 - 1.33)
= 7.5 + 3(4.67)
= 7.5 + 14.01
= 21.51
So, 12 - 3 y ÷ 2 + y( 2 y - 4 ÷ y ) for y = 3 is 21.51.
Answer: -.2
Step-by-step explanation: you plug in 3 where every y is. You get 12-9 divided by 2 plus 3 times 6 minus 4/3 or 4/2 + 3(6-4/3)
