The value of xy = 1800
<u>Step-by-step explanation:</u>
The product of x and y can be found by using the formula,
Greatest common factor of x and y × least common multiple of x and y
That is,
GCD of x & y multiplied by LCM of x & y we will get xy.
xy = 10 × 180 = 1800
Thus we can conclude the value of xy = 1800
Answer:
y = -2 x = 0
Step-by-step explanation:
1. 3x-4y = 8
2. 18-5y = 10
Multiply equation 1 by 6
3. 18x-24y = 48
Subtract equation 2 from equation 3
4. -19y = 38
y = 38/-19
y = -2
Sub y = -2 back into equation 1
3x-4(-2) = 8
3x + 8 = 8
3x = 0
x = 0/3
x = 0
Answer: Total cost =$24338.95
Step-by-step explanation:
The new car costs $19,820.00.
He has to pay 17.25% in taxes based off the cost of the car. This means 17.25% of $19,820.00
=(17.25/100)×19,820.00
=0.1725 ×19820.00 = $3418.95
Cost of taxes = $3418.95
If he also purchases an extended warranty for $1,100.00
Cost of taxes plus extended warranty
= $3418.95 + $1,100.00 = $4518.95
what is a reasonable estimate for the total price of the car? This means the actual cost of the new car + Cost of taxes + cost of extended warranty.
Total cost = $19,820.00 +$3418.95 + $1,100.00= $24338.95
