A restaurant bill comes to 28.35. Find the total cost if the tax is 6.25% And a 20% tip is left on the amount before tax.

dezoksy [38]

It comes out to $35.791875. To find the tip: 28.25 x 0.20 = 5.67
Tax: 28.35 x 0.0625 = 1.771875
1.771875 + 5.67 + 28.35 = $35.791875. The problem probably asks you to round your answer to the nearest cent, so $35.79

What is 13x -4+100=180

Naddika [18.5K]

Answer: x = 6.46153846

Step-by-step explanation:

We are given the equation 13x - 4 +100 = 180, and we must find the value of x. In order to do that get x on on one side by itself and a constant on the other side by itself.

This first step is to combine like terms. 13x is by itself. -4 + 100 = 96. This gives us the equation 13x +96 = 180.

In order to get x by itself, subtract 96 from each side of the equation. This gives us the equation 13x = 84.

Next, divide each side by 13 to find x. This gives us x = 6.46153846

$13x - 4 +100=180$

$13x + 96 = 180$

$13x = 84$

$x = 6.46153856$

Hope this helps! Have a nice day!

Algebra help

Vilka [71]

To determine the correct ordered pairs which will agree with the function, we can substitute values to the function and see whether it agree with each other. We do as follows:

(0,1)
 f(x)=128(0.5)^0
 f(x)=128

(1,64)
 f(x)=128(0.5)^1
f(x) = 64 <--------CORRECT ANSWER

(3,16)
 f(x)=128(0.5)^3
f(x) = 16 <--------CORRECT ANSWER

(8,0.5)
 f(x)=128(0.5)^8
f(x) = 1/2

Hope this answers the question. Have a nice day.
