We're measuring a quantity of pure detergent.
We start with 11 gallons of an 18% solution. 18% of that, or 1.98 gallons, is pure detergent, and the rest of these 11 gal. is water: 9.02 gal. We will add x gallons of water to this solution to obtain (11+x) gallons of a 12% solution.
We need to find x to satisfy this equation:
(11 gallons + x)(0.12) = (11 gallons)(0.18)
Div. both sides by 0.12, we get (11 gallons + x) = (11 gallons)(1.5)
Mult. both sides by 10, we get 110 gallons + 10x = (11 gallons)(15)
Then 10x = 165 gallons - 110 gallons, or 55 gallons.
Div. both sides by 10, we get x = 5.5 gallons (answer)
Answer:
it will be the second answer
Step-by-step explanation:
if 2 and 6 are the same, that make the opposing angle of the angles 2 and 6 the same which makes the other angles same which make the two lines parallel
f(x) = 9x-8
g(x) = x^3
(g°f) = (9x-8)^3
(g°f)(1) = (9(1)-8)^3 = (9-8)^3 = 1^3 = 1
It would be 2 2/25, so it would be d.

Step-by-step explanation:
6*68=408
------------------
48/10=4.8
----------------
3.8=x/7.7
x=3.8*7.7x
x=29.26
---------------
x+5.1=13.4
x=13.4-5.1
x=8.3
---------------
8x=64
x=64/8
x=8

22=m+1
m=22-1
m=21
----------
45-4x for x=5
45-4(5)=45-20=25
