First you subtract 9 from both sides, so you get -2x=26
Then you divide both sides by -2 which is x=-13
So your answer is -13.

Hence the number of packages of screws in each shipping box is: 469
Hence option (B) is correct.
Answer:
∠PQS= 3(x +5)
Step-by-step explanation:
∠PQR = 5x + 25
∠SQR+∠PQS= 5x+25
∠PQS = ∠PQR-∠SQR
∠PQS= (5x + 25 )-(2x + 10)
∠PQS = 5x+25 -2x-10
∠PQS= 3x +15
∠PQS= 3(x +5)
13. 81.64
14. 803.84
15. 153.83
16. 753.6
you just use circumference and area formulas for a circle
