Answer:
The correct answer is the sales tax charged is $5.61 for $66 dinner at 8.5% tax rate.
Step-by-step explanation:
Cost of the dinner is $22. Tax levied on it is $1.87
Let x% is the rate of tax in the city.
Therefore, x% of 22 = 1.87
⇒ x = 1.87 × 
= 8.5
Therefore 8.5% is the tax rate in the city on foods.
Now another dinner costs $66.
Tax levied on it at the same percentage is given by 8.5% of 66 = $5.61.
Thus $5.61 as sales tax would be charged for a $66 dinner.
Answer:
a = ± 4
Step-by-step explanation:
Expressing the proportion in fractional form
= 
( cross- multiply )
(a -1 )(a + 1) = 15 ← expand factors on left side
a² - 1 = 15 ( add 1 to both sides )
a² = 16 ( take the square root of both sides )
a = ± 
= ± 4
Straight line = 180, so 180-100=80, a triangle = 180, x equals to 180-(70+80) =30, the answer is a
(12x^3-4x^2+8x)/(-2x) The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:
-6x^2+2x-4 and we can now also factor out -2
-2(3x^2-x+2)
Answer:
x<_ 4
Step-by-step explanation:
first you distribute 5 to equal 5-35x+5 then you would carry the non variables to one side to be -35x>_-140 and the you would flip the sides because te variable is negative so it would be -35x<_ -140 the divid to get x<_4
