The mid point of the given interval can be determined by the

Midpoint \ = \frac{Initial\ Mean\ length\ +Final\ Mean\ length }{2}  \\Midpoint \ = \frac{4.1\ +\ 5.3\  }{2}  \\Midpoint \ = \frac{9.4 }{2}  \\Midpoint \ =4.7\\

What is the solution to the equation 7(a – 10) = 13 – 2(2a 3)?
geniusboy [140]
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
