Question

3 1/8(-y+8)-4 5/8(y-16) при y= -0,6

Answer 1

Ответ:

103,65

Пошаговое объяснение:

25/8(-y + 8) - 37/8(y - 16) = -25y/8 + 25 - 37y/8 + 74 = -62y/8 + 99 =

= -62/8 * (-6/10) + 99 = 4,65 + 99 = 103,65

Answer 2

To evaluate the expression 3 1/8(-y+8)-4 5/8(y-16) for y = -0.6, we need to substitute the value of y into the expression and simplify it. Let's break it down step by step:

Step 1: Convert the mixed numbers to improper fractions. 3 1/8 = (3 * 8 + 1) / 8 = 25 / 8 4 5/8 = (4 * 8 + 5) / 8 = 37 / 8

Step 2: Substitute the value of y into the expression. 3 1/8(-y + 8) - 4 5/8(y - 16) = (25 / 8) * (-(-0.6) + 8) - (37 / 8) * (-0.6 - 16)

Step 3: Simplify the expression. = (25 / 8) * (0.6 + 8) - (37 / 8) * (-0.6 - 16) = (25 / 8) * (8.6) - (37 / 8) * (-16.6) = 215 / 8 - (37 * (-16.6)) / 8 = 215 / 8 + (37 * 16.6) / 8 = 215 / 8 + 610.2 / 8 = (215 + 610.2) / 8 = 825.2 / 8 = 103.15

Therefore, when y = -0.6, the value of the expression 3 1/8(-y + 8) - 4 5/8(y - 16) is approximately 103.15.
