Answer:
16/19
Step-by-step explanation:
I believe you are referring to this equation: (9u-11)/2 = (19u +11)/3. To solve this step-by-step, first, multiply each side by 6 which is the least common denominator of 2 and 3. This then results to: 27u - 33 = 38u + 22. Second, combine like terms on one side such that: 11u = -55. Finally, the value for u is calculated to be -5.

Answer:
329.91 cm^2
Step-by-step explanation:
A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.
Your answer
Given data
inner radius= 8cm
area= πr^2
area= 3.142*8^2
area= 3.142*16
area= 50.272 cm^2
outer radius= 11cm
area= πr^2
area= 3.142*11^2
area= 3.142*121
area= 380.182 cm^2
Hence the area of the shaded part is
=380.182-50.272
=329.91 cm^2
