In a science experiment, you make foam by adding 1 tablespoon yeast and 3 tablespoons water to every 8 tablespoons hydrogen peroxide. 1. Represent the ratio using a tape diagram?
2. You use 3 more tablespoons of water than yeast. How many tablespoons of each ingredient do you use to make your foam?

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
