Afarmer has 191 sheep and a number of lambs
19 sheep have 3 lambs each
117 sheep have 2 lambs each
all the other sheep have 1 lamb each
how many lambs are there altogether?
with explanation !

19 sheep have 3 lambs each means 19x3=57 lamps
Plus
117 sheep have 2 lambs each means 117x2=234 Lamps
Plus
All the other sheep have 1 lamb each means (191-19-117)=55
Equal:
19x3+117x2+(191-19-117)=57+234+55=346 Lamps

OKay So...  You have To Write 3  19 times and add it then For the Next one 2 117 times ( i dont think you should really do that  just Mutiply ) and then 
 And then the rest of the sheep ( 55 sheep left ) have 1 lamb So then add

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
