Answer: 7 4/9
Step-by-step explanation:
Find least common denominator of 3 and 9, which is 9. So, 11 1/9 - 3 6/9 = 7 4/9
3x - 5y = 18 over
-10x + 5y = 10
Add them because the 5y's have the right symbols for us to add
-7x = 28
Divide
x = -4
Now you can plug in -4 for x in one equation, I would use the first equation!
3(-4) - 5y = 18
-12 - 5y = 18
Add 12
-5y = 30
Divide
y = -6
Your solutions are going to be:
x = -4
y = -6
To check your work plug x and y into one equation:
3(-4) - 5(-6) = 18
-12 + 30 = 18
18 = 18
Since 18 does equal 18 you know that your solution's work!
Answer:The total cost for the car including tax is $27423.75
Step-by-step explanation:
The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be
6.5/100 × 25750 = 0.065 × 25750 = 1673.75
The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes
25750 + 1673.75 = $27423.75
