The larger of two numbers is 9 less than four times the smaller number if the sum of the two numbers is 26. What is the smaller number?

7

Step-by-step explanation:

l = larger number

s = smaller number

l = 4s - 9

l + s = 26

so 4s - 9 + (s) = 26

simplify--> 5s - 9 = 26

--> 5s = 35

---> s = 7

substitute 7 for s to find l

l + 7 = 26

l = 19

is there any attachment? what are the equations?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
