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

Answer: I would think
6-0
12-1
30-2
Step-by-step explanation:
Answer:
Bag: 800/100 = 8*15 = 120
Umbrella: 400/100 = 4*15 = 60
120 - 60 = 60
The shopkeeper has gained 60 from the transaction
I believe it is d.
Equation is y= 1/2x.
When a number or fraction is next to a variable that means to multiply.
So let’s replace the variable,x, with 6.
If you multiply 1/2 by 6, you get 3.
If you multiply 1/2 by 24 you get 12.
