1) 5(x-1) = - 20        =>     5x - 5 = -20 =>  5x = -15      => x = -3
2) 3y = -15     => y = -5

Your food bill at a restaurant is $30. You leave a 20% tip. The sales tax is 6%. What is the total cost of the meal?
ohaa [14]
The total cost of the meal is $37.80

Given:
Food bill = $30
tip = 20%
sales tax = 6%

Tip and sales tax must be based on the food bill.

Tip = $30 x 20% = $6
Sales Tax = $30 x 6% = $1.80

Food bill :   30.00
Tip               6.00
Sales tax  <u>   1.80</u>
Total cost 37.80

Autumn measures the angle of elevation from the ground to the top of an 18-foot tall tree as 27°. To the nearest tenth of a foot
leonid [27]

Answer: she is 35.3 feet from the tree.

Step-by-step explanation:

Assuming her line of sight to the top of the tree is a straight line, then a right angle triangle is formed. The height of the tree, h represents the opposite side of the right angle triangle. Her distance, h from the tree represents the adjacent side of the right angle triangle. To determine h, we would apply the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan 27 = 18/h

h = 18/tan27 = 18/0.51

h = 35.3 feet
