Question:
What is the equation for the following statement,"One-half of a number decreased by 3 is 21.
Answer:
<em>half the number = x/2 </em>
<em>decreased by 3 </em>
<em>(x/2) -3 =21</em>
<em>=48</em>
Let's assign a variable x to the number of multiples for each pound of dry mix and water. With that being the said, the question for finding the total pounds would be:
Total pounds = x*Pounds of dry mix + x*Pounds of water
Total pounds = 60x + 8x = 68x = 14 + 1/6 = 85/6
x = 85/6 / 68
x = 5/24
Thus, the pounds of dry mix is 60*5/24 = 25/2 lbs, while the pounds of water is 8*5/24 = 5/3 pounds.
Answer:
2/3&1/6
2/3- 1/6
the LCM for 3 and 6 is 6
=(2x6)/(3x6) -(1x6)/(6x6)
=4/6-1/6
=(4-1)/6
find the difference
= 3/6
=1/2
2/3-1/6= 1/2
By using LCM method, 1/2 is the equivalent fraction by subtracting 1/6 from 2/3.
2/3&1/6
2/3- 1/6
cross multiply
2x6-1x3/3x6
simplify
12-3/18
=9/18
= 1/2
2/3-1/6 = 1/2
By using cross multiplication method, 1/2 is the difference between two fractions 2/3 and 1/6.

Answer:
<em>4,524 gallons</em>
Step-by-step explanation:
The volume of any cylinder is
π (radius)² (height) .
The pool's radius is 1/2 its diameter = 8 ft. So its volume is
π (8 ft)² (3 ft)
= π · (64 ft²) · (3 ft)
= π · 192 ft³
= 603.2 ft³ .
(603 ft³) · (7.5 gal / 1 ft³) = 4,524 gallons
Hope this helps :D
