Assume each pair of figures, the second polygon is similar to the first, with the same orientation. set up equations to find the lengths of the sides labeled by variables solve each equation and find the labeled lengths find any remaining lengths of either figure.

5.

6 / t = 9 / (t+2)

9t = 6t + 12

3t = 12

t = 4   answer

The remaining length:-

6 / 4 = 11 / x

6x = 44 so x = 7.33  answer

6.  8 / w = 6 / (w - 5)

6w = 8w - 40

2w = 40 so w = 20 answer

The side marked w - 5  = 20-5 = 15 answer

8/14 = 20/x giving the top side =  35  answer

i would have to say it is c.

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
