Answer:

$x = p( m - n)$

Step-by-step explanation:

$m = n + \frac{x}{p} \\ m - n = \frac{x}{p} \\ p(m - n) = \frac{x}{p} \times p \\ \\ x = p(m - n)$

Answer:

X as a subject = x = p(m - n)

Step-by-step explanation:

m = n+ x/p

m - n = x/p

p(m - n) = x

So, x = p(m - n)

A bag of jelly beans contains 10 red,6 green,7 yellow, and 5 orange jelly beans.What is the probability of randomly choosing a r

lilavasa [31]

Answer:

$\text{The Probability is = }\frac{125}{5488}\approx 0.02$

Step-by-step explanation:

No. of red jelly = 10

No. of green jelly = 6

No. of yellow jelly = 7

No. of orange jelly = 5

Total number of jelly = 10 + 6 + 7 + 5 = 28

$\text{So, Probability of choosing red jelly, P(R) = }\frac{10}{28}=\frac{5}{14}\\\\\text{So, Probability of choosing orange jelly, P(O) = }\frac{5}{28}\\\\\text{Now, Probability of choosing first red , then red and then orange jelly}\\\text{on replacing each jelly after choosing, }\\\\P(R,R,O) = \frac{5}{14}\times \frac{5}{14}\times \frac{5}{28}=\frac{125}{5488}\approx 0.02$

Hence, the required probability is 0.02 or 2 %

PLEASE HELP!! this is due really soon

Answer: There are 467 students at Holmes Junior High.

There are 342 students at Harper Junior High.

_________________________________________________

Step-by-step explanation:

_________________________________________________

Let " x" represent the number of students at Harper Jr. High.

Holmes Junior has: " (x + 125) " students .

Harper Junior High has: " x" students:

_________________________________________________

Together, the total number of students equal: " 809 " students.

so: " x + (x + 125) = 809 " .

We want to solve for "x" and " (x + 125)" .

We want to solve for "x" ;

then we can solve for " (x + 125) " by adding "125" ;

to our "solved value for "x" ;

____________________________________________

x + (x + 125) = 809 .

→ 1x + 1x + 125 = 809 ;

→ 2x + 125 = 809 ;

Now, subtract "125" from each side of the equation:

→ 2x + 125 - 125 = 809 - 125 ;

→ 2x = 684 ;

Now, divide each side of the equation by "2" ;

to isolate: "x" on one side of the equation; & to solve for "x" ;

→ 2x/ 2 = 684 / 2 ;

to get:

→ x = 342 ; which is the total number of students at Harper Jr. High.

Now, to solve for: " (x + 125)" ;

Plug in: "342" for "x" ;

→ " (342 + 125) " = " 467 " '

→ which is the total number of students at Holmes Jr. High.

_________________________________________________

Do our answers make sense:

Does: " 342 + 467 =? 809 ?? " ;

→ Yes!

_________________________________________________

Answer: There are 467 students at Holmes Junior High.

There are 342 students at Harper Junior High.
