Answer:

The given expression $8a+3b-10+c^2$ at a = 2 , b = 5 and c = 4 is 37.

Step-by-step explanation:

Given : expression $8a+3b-10+c^2$

We have to evaluate the given expression $8a+3b-10+c^2$ at a = 2 , b = 5 and c = 4

Consider the given expression $8a+3b-10+c^2$

Substitute, a = 2 , b= 5 and c = 4

We have,

$=8(2)+3(5)-10+(4)^2$

Simplify, we have,

$=16+13-10+16$

We get,

= 37

So, The given expression $a+3b-10+c^2$ at a = 2 , b = 5 and c = 4 is 37.

You and your friend each collect rocks and fessis your friend collects three times as many roots and half as many fossils as you

n200080 [17]

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 (1/2) = 15

3x + (y/2) = 15-------------------(2)

Substituting (1) in (2)

3(25 - y) + (y/2) = 15

75 - 3y + (y/2) = 15

Grouping the like terms we get,

75 - 15 = 3y = (y/2)

60 = ( 6y - y /2)

60 x 2 = 6y -y

120 = 5y

y = 120/5

y = 24

Substituting y value in equation(1) we get

x = 25 - 24

x= 1

y= 24

Friends collects 3 times rock

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

Also he collects half as many fossils

That is

y/2 = 24/2 = 12 fossils

Hope this help you! :)
