Answer:

See Below

Step-by-step explanation:

This is very simple, but I can help more if you're stuck.

Take the number of pounds multiplied by the cost per pound.

For example, if I had 5 pounds of peaches, and they are $2 per pound...

5 pounds * $2 per pound = $10

Try it on your own :)

Answer:

The value of r= $\frac{-106}{47}$

The value of x= $\frac{83}{32}$

Step-by-step explanation:

Given that,

A) $\frac{2r-2}{7r+10} = \frac{9}{8}$

Now,

$\frac{2r-2}{7r+10} = \frac{9}{8}$

8(2r-2)=9(7r+10)

16r-16=63r+90

-16-90=63r-16r

-(16+90)=47r

-106=47r

r= $\frac{-106}{47}$

B) $\frac{x+4}{9} = \frac{3(x-2)-1}{5}$

Now,

$\frac{x+4}{9} = \frac{3(x-2)-1}{5}$

5(x+5)=9[3(x-2)-1]

5x+25=9[3x-6-1]

5x+25=9[3x-7]

5x+25=27x-63

25+63=27x+5x

83=32x

x= $\frac{83}{32}$

Sample space

jasenka [17]

Considering it's concept, it is found that the number of outcomes in the sample space is of 9.

<h3>What is the sample space of an experiment?</h3>

The sample space is the <u>set that contains all possible outcomes for an experiment</u>.

In this problem, there are 2 trials, each with 3 possible outcomes(red, blue or green), hence the <u>number of possible outcomes</u> is given by:

N = 3² = 9.
