Black queen 2/52 and greater than 4 on a cube 2/6
Answer:
A
Step-by-step explanation:
If you were to multiply the top by 7 then add you would cancel out the x and if you were to multiply the bottom by 6 then when you use the subtraction method you multiply the top by negative and if that were to happen you would do -6x + -6x which would cancel nothing out. But if you just add the two equations nothing would cancel out.
Hope this helped!
Answer:

820 Students
Step-by-step explanation:
80t+500=30t+700
-30t -30t
50t+500=700
-500 -500
50t=200
/50 /50
T=4
A=80(4)+500=820
B=30(4)+700=820
