\huge\text{Hey there!}

\large\boxed{\rm{\dfrac{ab^2 - 4}{10}}}

\large\boxed{\rm{\rightarrow\dfrac{\bold{4(6)}^2 -4}{10}}}

\large\boxed{\rm{6^2}}

\large\boxed{\rm{= 6 \times6}}

\large\boxed{\rm{= \bf 36}}

\large\boxed{\rm{\rightarrow\dfrac{4(\bold{36)}- 4}{10}}}}

\large\boxed{\rm{4(36)}}

\large\boxed{\rm{= \bf 144}}}

\large\boxed{\rm{\rightarrow\dfrac{\bold{144} - 4}{10}}}

\large\boxed{\rm{\bold{144} - 4}}

\large\boxed{= \rm{\bf 140}}}

\large\boxed{\rm{\rightarrow\dfrac{\bold{140}}{10}}}

\large\boxed{\rm{= \bf 14}}

\huge\boxed{\rm{Therefore, your\ answer\ is: \mathsf{14}}}\huge\checkmark

You order two tacos and a salad. the salad costs 2.50.you pay 8% sales tax and leave a $3 tip. you pay a total of 13.80 how much
riadik2000 [5.3K]
Given:Price of one taco = x; price of 2 tacos = 2xPrice of salad = $2.50Sales tax = 8% of the combined price of two tacos and a salad, namely .08(2x + 2.50)Tip = constant fee = $3.00Total bill = $13.80 Therefore the equation becomes
2x + 2.50 + .08(2x + 2.50) + 3 = 13.80 Solutions: 2x + 2.50 + .16x + .20 + 3 = 13.80 (using the distributive property to multiply 2x and 2.5 by .08).2.16x + 2.70 + 3 = 13.80 (combining like terms)2.16x + 5.70 = 13.80 (combining like terms)2.16x + 5.70 = 13.80 - 5.70 (subtraction property of equality)2.16x = 8.10x = 8.10/2.16 = 3.75 (division property of equality)
The cost of a single taco is $3.75

What is the length of EF in the right triangle below?
Tema [17]

Answer:

A

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to find EF

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

EF² + DF² = DE² ← substitute values

EF² + 12² = 18², that is

EF² + 144 = 324 ( subtract 144 from both sides )

EF² = 180 ( take the square root of both sides )

EF = \sqrt{180} → A
