Answer 3

To find the value of 15×(3х-1) when 8×(5х-2) is equal to 0, we need to solve for the value of 'x' in the equation 8×(5х-2) = 0 first.

The equation given is: 8×(5х-2) = 0

Now, to solve for 'x', set the expression inside the parentheses equal to zero: 5x - 2 = 0

Now, add 2 to both sides to isolate 'x': 5x = 2

Finally, divide both sides by 5 to find the value of 'x': x = 2/5

Now that we have the value of 'x', we can use it to find the value of 15×(3х-1):

15×(3х-1) = 15×(3×(2/5) - 1)

Now, simplify the expression inside the parentheses:

15×(3×(2/5) - 1) = 15×(6/5 - 1)

Now, find the common denominator for the fractions:

15×(6/5 - 5/5) = 15×(1/5)

Finally, multiply:

15×(1/5) = 3

So, 15×(3х-1) is equal to 3.
