Question

3y+(16-y)•2+3,5y при y = 8

Answer 1

3*8+(16-8)*2+3,5*8=24+8*2+28=24+16+28=68

Answer 2

3*8+(16-8)*2+3,5*8=68
1)16-8=8
2)8*2=16
3)3*8=24
4)3,5*8=28
5)24+16=40
6)40+28=68

Answer 3

To evaluate the expression for y = 8, we substitute 8 for y in the expression and simplify:

3y + (16 - y) * 2 + 3.5y = 3(8) + (16 - 8) * 2 + 3.5(8) // Substitute y = 8 = 24 + 8 * 2 + 28 = 24 + 16 + 28 = 68

Therefore, when y = 8, the value of the expression 3y + (16-y) * 2 + 3.5y is 68.
