Drag a statement or reason to each box to complete this proof. If −5(x+8)=−25, then x=−3.

Step-by-step explanation:

Prove that,

−5(x+8) = −25 then x = -3

−5(x+8) = −25

By distributive property,

-5x - 40 = -25

Adding 40 to both sides, that is, Additive property of equality

-5x - 40 + 40 = -25 + 40

-5x = 15

Divide both sides by -5, that is Division property of equality

-5x / -5 = 15 / -5

x = -3

Hence, x = -3 has been proved

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.
