<h3>Given</h3>
... r + 7 = 9
<h3>Find</h3>
... r
<h3>Solution</h3>
Subtract 7 from both sides of the equation.
... r + 7 - 7 = 9 - 7
... r = 2 . . . . . . simplify
Expressed as a solution set, this may look like ...
... r ∈ {2}

Answer:
PT = 14
Step-by-step explanation:
Given that T is the midpoint of PQ, then
TQ = PT ← substitute values
5x - 6 = 3x + 2 ( subtract 3x from both sides )
2x - 6 = 2 ( add 6 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Hence
PT = 3x + 2 = (3 × 4) + 2 = 12 + 2 = 14
Answer:
The answer is -1.
Step-by-step explanation:
This is because if you multiply two negatives together, it becomes a positive. But if you do -1*-1*-1*-1*-1*-1*-1, it would equal -1. Hope this helps
