I believe a minimum of 7 trips over the bridge is required.
Answer:
X > - 7.5
Step-by-step explanation:
1/X + 1/3 < 1/5
1/X + 1/3 < 1/5
Step one:collect like terms
1/X < 1/5 -1/3
Step two: Find the L.C.M of the R.H.S which is 15
1/X < 3-5/15
1/X < -2/15
1/X < -2/15
Step three: Take the reciprocal of both sides.
X < 15/-2
Dividing through by -2 changes the inequality sign, Hence
X > -7.5
Let's say TX = 7. TX is equal to XY, so this means TX = XY = 7. So we know XY equals 7, and it's given that XY = YZ. Substitute in 7 for XY and you get 7 = YZ. Since Both TX and YZ are equal to 7, they are equal.
