This is cross multipication.  Multiply 117 times 36 together for that you would use a calculator. You get 4221. Next step is to multiply x and 12 together that would be 12x.

4221= 12x

Divide  by 12 on both sides:

x= 351

351 is # of trouts in the lake .

[I have no idea how to do this]
jekas [21]

Answer:

We have 16 ounces of 3% H2O2

How many ounces of 30% H2O2 do we add to make a 10% H2O2 solution?

let x = amount of ounces of 30% H2O2 to add

.03 * 16 + .30x = .10 * (16 + x)

.48 + .30x = 1.6 + .1x

.2x = 1.12

x = 5.6 ounces

Tyler is 9 years old his sister Olivia is 6 years less than twice his age writ a numerical expression for Olivia’s age
liberstina [14]
Hello there!

The following will show you

T = tyler

O = olivia


O = 2t - 6

when you include numbers, it is represented by:

O = (2 * 9) - 6

Now, let's solve this to find out just how old Olivia is.

2 * 9 = 18

18 - 6 = 12

Olivia is 12

This means that olivia is 3 years older than tyler

I hope I helped!
