Help Me and Explain THX! You and your friend each collect rocks and fossils. Your friend collects
three times as many rocks and half as many fossils as you. You collect 20
objects. Your friend collects 15 objects. How many rocks and how many
fossils do you each collect?

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

the answer is  

a.

4,624π mm2
