Answer:

  x = -4

Step-by-step explanation:

20 greater than (8x+5) is 8x+5+20 = 8x+25. We are told this is the value of 2x+1:

  2x+1 = 8x+25

  -24 = 6x . . . . . . subtract 2x+25

  -4 = x . . . . . . . . divide by 6

The value of x is -4.

Given: p: x – 5 =10 q: 4x + 1 = 61 Which is the inverse of p → q? If x – 5 ≠ 10, then 4x + 1 ≠ 61. If 4x + 1 ≠ 61, then x – 5 ≠

Answer: <span>If x – 5 ≠ 10, then 4x + 1 ≠ 61

Justification:
</span>
1) The inverse of a conditional is negating both the hipothesis and the conclusion of the conditional, keeping the same sense of the implication.

2) This is the scheme (the symbol ~ is used to negate)

conditional: p → q
hypothesis: p
conclusion: q

negated hypothesis: ~p
negated conclusion: ~ q

inverse conditional: ~p → ~q

3) So, for the hypotheis <span>p: x – 5 =10 and the conclusion q: 4x + 1 = 61, the conditional p→ q is:

 if x - 5 = 10 then 4x + 1 = 61.

And the inverse is negating both the x - 5 = 10 and 4x + 1 = 61, leading to:

If x – 5 ≠ 10, then 4x + 1 ≠ 61, which is the answer.</span>
