Answer:
(x, y) = (3.5, -4)
Step-by-step explanation:
Elimination is easiest if one of the coefficients of a variable is a multiple of the other coefficient of the variable. Here, we have x-coefficients of 4 and 8, so it will be easiest to eliminate x.
Subtract the second equation from 2 times the first.
2(4x +7y) -(8x +5y) = 2(-14) -(8)
9y = -36 . . . . . simplify
y = -4 . . . . . . . divide by 9
4x +7(-4) = -14 . . . . substitute for y in the first equation
4x = 14 . . . . . . . add 28
x = 3.5 . . . . divide by 4
The solution is (x, y) = (3.5, -4).
Answer:
Step-by-step explanation:
To find tax on something you multiply the base price by the tax percentage. So if something is 100 dollars and tax is 5 percent (or .05 in decimal form), you would add 5 dollars to the price. because 100*.05=5.
If we assume 6% as the tax then we multiply 22.50*.06 = 1.35, so you will add 1.35 to the price. That means the new price is 22.50 + 1.35 = 23.85.
It's just asking for what the tax is though so the answer is 1.35 at 6%. The question does say the tax is over 6% though, so that means the tax will only go up from there if the tax is over 6%
