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 .
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

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!
