Choose three different chains of energy conversions that you use at home or at school to accomplish tasks in your daily activities.

There are different energy conversions which we encounter in day to day life. Some of them are:

1) We use chemical energy in the food to convert it into mechanical and kinetic energy which we need for walking to the school.

2) We use chemical energy to be transferred into electrical energy which is converted to light energy in our bulbs so that we can see.

3) We convert electrical energy in the toaster to thermal energy to make breakfast.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
