You and your friend each collect rocks and fossils. Your friend collects three times as many rocks and half as many fossils as y
tino4ka555 [31]

Answer:

Number of rocks and fossils collected by you is 1 and  24 respectively

Number of rocks and fossils collected by your friend is 3 and 12 respectively

Step-by-step explanation:

Let  the number of Rocks you collect be x

Let  the number of Fossils you collect be y

Then the total number pf objects you collected will be

x + y = 25

x = 25 - y------------------------------(1)

Your friend collects three times as many rocks and half as many fossils as you.

This can be written as

3x + y(\frac{1}{2}) = 15

3x + (\frac{y}{2}) = 15-------------------(2)

Substituting (1) in (2)

3(25 -y) + (\frac{y}{2}) = 15

75 - 3y + (\frac{y}{2}) = 15

Grouping the like terms we get,

75 - 15 = 3y - (\frac{y}{2})

60= \frac{6y-y}{2})

60 \times 2= 6y-y

120= 5y

y = \frac{120}{5}

y= 24

Substituting  y value in equation(1) we get

x = 25 - 24

x= 1

Friends collects 3 times rock

so collects 3x =3(1) = 3rocks

Also he collects half as many fossils

That is

\frac{y}{2} = \frac{24}{2} =12 fossils
