5.25, or 5 and 1 quarter (5 1/4)
1 plus 5
10 + 10 + 10 + 5 + 5 +1 = 41.

10u7 - 45u6 + 45u5 = 5u5 (2u2 - 9u + 9) = 5u5 (2u - 3) (u - 3)
(4u - 5)(2u - 1)
23 + 5u = 17Subtract 17 23 from both sides:5u = -6Divide both sides by 5:u = -6/5
r = 5k + 5ur - 5u = 5kk = r/5 - u

in the question 7-5u=-43, the answer to u is -45, because 7-5=2, 2x-45=-43. so u=-43.
1+1+1x1+5 =1+1+1+5=8
1 + 1 + 1 + 1/4 + 5/5 = 4 and 1/4
1+1+1+1+1 the answer is 5 The answer is 5.
(Double plus 1 of 5) plus 5 = 16 Double plus 1 of (5 plus 5) = 21
