Given the set of equations:
2x + y = 10
y = 3x
Let's solve for x and y.
Here, let's use substitution method.
Substitute 3x for y in equation 1:
2x + y = 10
2x + 3x = 10
5x = 10
Divide both sides by 5:
In equation 2, substitute 2 for x to find y.
y = 3x
y = 3(2)
y = 6
Therefore, we have:
x = 2 and y = 6
ANSWER:
x = 2, y = 6
Answer:
250 families
Step-by-step explanation:
Given that ;
Amount of water used by the golf course is 80,000,000 gallons per day
Amount of water used a family of four is 325,851 gallons per year
It is clear here that the amount of water used per day to water the golf course can be used by several families of four per year because a family of four just requires 325,851 gallons of water per year.
To find the number of families of four, you divide the amount used to water the golf course with the amount used by a single family of four.
<u>Number of families</u>
=246 to the nearest ten will be 250 because the value in the ones position is greater than 5 thus 246 changes to 250
