Answer: x = - 12
8x + 45 = 10x + 69
⇔ 10x - 8x = 45 - 69
⇔ 2x = -24
⇔ x = -12
Step-by-step explanation:
1000/2=500
500*8=4,000
So the plane could go 4,000 miles in 8 hours

Answer:
A.
41.125π ≈ 129
149.875π ≈ 471
Step-by-step explanation:
Surface area of smaller ganza:
3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325
1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)
Surface area of larger ganza:
5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925
2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)
π
129/3.14 = 41.125
471/3.14 = 149.875
