Every package of a certain toy also includes  2 batteries. are the number of toys and number of batteries in a proportional relationship? if so, what are the two constants of proportionality? if not, explain your reasoning. use  t  for the number of toys and  bfor the number of batteries to write two equations relating the two variables. b=t=

It says every package of toy contains 2 batteries.

It means 1 Toy requires 2 Batteries to run.

Yes, there is a proportional relationship between number of toys and number of batteries.

If 't' represents number of toys and 'b' represents number of batteries. Then relationship between toys and batteries can be written as follows:-

Number of Batteries = 2 x Number of Toys

OR

Number of Toys = 1/2 x Number of Batteries

Hence, b = 2t OR t = 1/2 b

As given, that every package of a certain toy also includes 2 batteries.

1. So, yes the number of toys and number of batteries in a proportional relationship.

If there is 1 toy, there are 2 batteries.

If there are 2 toys, there will be 4 batteries.

If there are 4 toys, there will be 8 batteries.

And 2 and 1/2 are the constants of proportionality .

2. Let t for the number of toys and b for the number of batteries ;

So, the two equations relating the two variables.

b=2t and t=1/2b

after simplifying it i got: -36.25 as my answer. hope that !

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
