17. explain whether 11t - 4t is equivalent to 4t - 11t.
support your answer by evaluating the expression for t = 2.

So Equation ( 1 )  is NOT Equivalent to Equation ( 2 )

Step-by-step explanation:

Given:

..............Equation ( 1 )

 ................Equation ( 2 )

To Find:

Whether Equation ( 1 )  is Equivalent to Equation ( 2 )

Support your answer by evaluating the expression for t = 2.

Solution:

For t=2 Equation ( 1 ) we get

For t=2 Equation ( 2 ) we get

From above we get two different values

So Equation ( 1 )  is NOT Equivalent to Equation ( 2 )

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
