Question

(4а-7а)/0,6 при а=8;-2 

Answer 1

(4a-7а)/0.6= -3а/0.6
при =8;( -3*8)/0.6=-24/0.6=-40
при=-2; (-3*-2)/0.6= 6/0.6=10

Answer 2

To evaluate the expression (4a - 7a) / 0.6 for the given values of a (a = 8 and a = -2), we substitute the values into the expression and calculate the result.

For a = 8: (4a - 7a) / 0.6 = (4 * 8 - 7 * 8) / 0.6 = (32 - 56) / 0.6 = -24 / 0.6 = -40

For a = -2: (4a - 7a) / 0.6 = (4 * -2 - 7 * -2) / 0.6 = (-8 + 14) / 0.6 = 6 / 0.6 = 10

Therefore, when a = 8, the result is -40, and when a = -2, the result is 10.
