Answer:
n = 112/13 = 8.615
Step-by-step explanation:
(3/8) n + 5n - 30 = (17/8)n - 2
(3/8)n +5n - (17/8)n = 30-2
(13/4)n = 28
n = 28 * 4/13
n = 112/13
n = 8.615
This doesn't make any sense

Answer:
92
Step-by-step explanation:
The maximum whole number that will round to 10 is 14, that is, it may be 4 more than the nearest 10.
If all three numbers are 4 more than the nearest 10, their maximum sum will be 12 more than the sum of the rounded numbers.
For example, consider the numbers 34, 34, 24. These have a sum of 92. When rounded to the nearest 10, their values are 30, 30, 20, which have a sum of 80.
The maximum sum of the three original whole numbers is 92.
Suppose an object starts moving at u and gains an acceleration of a. After time t, it gets a speed v after travelling a distance of s.
a = (v - u) / t => v - u = at
v = u + at
s = ut + 1/2(v - u) t
s = ut + 1/2 (at) t
s = ut + 1/2 at2
s = ut + 1/2 at2
v2 = (u + at)2
v2 =u2 + 2uat + a2t2
v2 = u2 + 2a (ut + 1/2 at2)
v2 = u2 + 2as
v2 = u2 + 2as
