a well-balanced scale ensures that if you place the same weight on both plates it will remain perfectly in balance. therefore, if in one of them you place 7 copper coins and 300 grams of rice, while in the other you place 5 copper coins exactly the same as the previous ones and 500 grams of seed, you observe that the scale remains in balance. how much weight is in the first plate?

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
