Answer:
multiply by 3 and divide by 2 to get 6x -y = 12.
Step-by-step explanation:
A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...
4(3/2)x -(2/3)(3/2)y = 8(3/2)
6x -y = 12
The first equation is
The second equation is
If you sum the two equations you'll cancel y:
And since the sum must be 11, we have y=9.
20.50 * 0.8 = $16.40
16.40 * 0.4 = $6.56
Final selling price = $6.56
Annually= per year
200 at 8% the first year would be
200 • 0.08 = 16 per year
2 years = 32 dollars in interest at the end of 2 years
Answer:
Simplified answer = 11.1 - 10y = 0
y = 1.11
Step-by-step explanation:
6 - 2y + (-8y) + 5.1 = 0
6 + 5.1 -2y -8y = 0
Add like terms
11.1 - 10y = 0
(This is simplified, but if you want to solve for y, continue)
11.1 - 10y = 0
÷10 ÷10
1.11 - y = 0
y = 1.11 because 1.11 - 1.11 is 0
I Hope That This Helps!
