Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
Answer:
The total sale price that Gechina paid was $5,274.71.
Step-by-step explanation:
Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:
100 - 35 = 65
(8,000 + 74.95 + 39.99) x 0.65 = X
8,114.94 x 0.65 = X
5,274.71 = X
Therefore, the total sale price that Gechina paid was $5,274.71.
Answer:
339 miles.
Step-by-step explanation:
Given:
A car rental agency advertised renting a car for $27.95 per day and 0.26$ per mile.
If Trevor rents this car for 4 days.
Question asked:
How many whole miles can he drive on a $200 budget?
Solution:
Total budget = $200
Trevor rents car for number of days = 4
As a car rental agency renting a car for $27.95 per day fixed charge, so Trevor must pay = Fixed charge per day 
number of days rented for
= $27.95 4
= $111.8
Remaining amount = $200 - $111.8 = $88.2
Now, to find number of miles he can travel, we will divide remaining amount by amount charged per mile
$88.2 
$0.26 = 339.23 miles
Therefore, he can drive 339 miles on a $200 budget
From the calculations, we can see that the number of beetles after three years is 11618 beetles.

What is an exponential problem?</h3>
The term "exponential problem" has to do with any problem in which the increase or decrease occurs exponentially.
In this case we have P = Poe^rt
Po = 10,000
r = 0.05
t = 3
P = 10,000 e^(0.05 * 3)
P= 11618 beetles
