Answer:
Unurewhat you need but, the equation of this is: 0.5x+4
where x is week(s)
You need to drain on the WASTE position, NOT the BACKWASH position. If you have a swimming pool sand filter and use the BACKWASH position you might end up losing sand in the process of draining. 2. CLOSE the skimmer valve so the filtration system is not pulling in air when the water level gets below the skimm
ength times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.
It would be web plato because thats how it is, i think.
Answer:
360 miles
Step-by-step explanation:
1 inch = 60 miles
6 inches = x
- to get this simply multiply 60*6
J+S=24 and J=S+6 represents the relationship between ages.
John is 15 years old and Sally is 9 years old.
Step-by-step explanation:
Let,
John's age = J
Sally's age = S
According to given statement, the sum of their ages is 24;
Eqn 1
John is 6 years older than Sally means we will add 6 in Sally's age;
Eqn 2
Putting value of J from Eqn 2 in Eqn 1;

Dividing both sides by 2

Putting S=9 in Eqn 2

J+S=24 and J=S+6 represents the relationship between ages.
John is 15 years old and Sally is 9 years old.
