Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
Answer: b = 4
Step-by-step explanation:
<u>Given</u>
4b + 5 = 1 + 5b
<u>Subtract 4b on both sides</u>
4b + 5 - 4b = 1 + 5b - 4b
5 = 1 + b
<u>Subtract 1 on both sides</u>
5 - 1 = 1 + b - 1
Hope this helps!! :)

Answer:
4/3π(0.973r³)
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Given the radius of dodge ball rd = r
radius of tennis ball rt = 0.3r
Taking their difference
Volume difference = 4/3πrd³ - 4/3πrt³
Volume difference = 4/3π(r)³ - 4/3π(0.3r)³
Volume difference = 4/3π(r³ - 0.027r³)
Volume difference = 4/3π(0.973r³)
Hence the differmce in volume is 4/3π(0.973r³)
