15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add 
gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to 
gallons, and the total volume increases to 
gallons.
To get a concentration of 8% in this diluted solution, we add gallons of water such that
Solve for .
To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
Area =l×w
15.4=7×w
15.4/7=7/7w
2.2=w
Therefore the length of the height or width is 2.2ft
Answer:
145 = w + 27
145 - 27 = 118
w = 118
Step-by-step explanation:
Use the subtraction method to solve problem like those!

8p=16 /8
p=2
2. 8j -5 +j=67
== 9j=72 /9
j=8
3. 3(2x-5)=4x+33 <--- =expand ()
6x-15=4x+33 ---> 2x=48
x=24
4. c=b-bx
get just x's on one side
c-b=bx
divide by b---> (c-b)/b=x
Answer:
the difference of 2 times d minus 3= 6
4 added to the difference of d minus 3= 4
the difference of d minus 3 divided by 2= 0
the quotient of 12 divided by the difference of 3 times d minus 3= 2
Step-by-step explanation:
2 times 3 equals 6. 3 minus 3 equals 0. 6-0=6
d minus 3 equals 0. 4+0 equals 4
3 minus d equals 0. 0 divided by two is 0
3 times d= 9. minus 3 = 6. 12 divided by 6 = 2
hope this helps! (:
