At a store, there is a display of 240 boxes of cereal. of the 240 boxes, 3/5 are brand a and 2/5 are brand b. how many boxes of brand b cereal must be added so that the display has 1/2 of each brand?

Which is an equation for the nth terms of the sequence 12,15,18,21

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Can someone explain to me how to do
