The plot: x meters wide and (x+30) meters long with an area of 15000 m^2. the equation you're searching for is:
x meters * (x+30) meters = 15000 m^2 or
x^2 + 30x m^2 = 15000 m^2 and
x^2 + 30x - 15000 = 0 <== that's the equation.
ans: x^2 + 30x - 15000 = 0
Answer:
6
Step-by-step explanation:
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Greg's daughter will have $533 in her piggy bank in a year
The money in the piggy bank would increase everyday by the amount put in it. There are seven days in a week. If he puts $0.75 everyday apart from on Sundays when we puts $5.75, the amount that would be in the piggy bank in a week is the sum of the money deposited each day.
Total amount in a week = total amount deposited from Monday to Saturday + amount deposited on Sunday
- Amount that Greg puts in 6 days : ($0.75 x 6) = $4.50
- Amount deposited on Sunday = $5.75
- Total amount = $5.75 + $4.50 = $10.25
The total amount Greg's daughter would have in a year is a function of the number of weeks in year and the total amount saved in a week
Total amount in a year = number of weeks in year x the total amount saved in a week
- Number of weeks in year = 52
- The total amount saved in a week = $10.25
$10.25 x 52 = $533
In order to determine how much Greg's daughter would have in a year, first determine how much she would have in a week. Multiply this amount by the number of weeks in a year
