Answer:
$86.50
Step-by-step explanation:
Let b represent the bill before tax and tip. Then the total is ...
b + 0.05b + 0.15b = 103.80
b(1.20) = 103.80 . . . . . . . . . . collect terms
b = 103.80/1.20 = 86.50 . . . divide by the coefficient of b
The bill before tax and tip was $86.50.
The slope of this line is 1 and the y-intercept is -2.
In order to find this, you need to put it in slope intercept form. This is done below for you.
3x - 3y = 6 -----> Subtract 3x from both sides
-3y = -3x + 6 -----> Divide by -3
y = x - 2
Now that you have this, you can find the slope by looking for the coefficient of x. In this case it is 1. You can find the intercept as the constant at the end, which is -2.

Answer:
25. If you look at angle B from the first figure you see a square that indicates a 90 degrees angle, thus the figure shown is a right triangle. You can also see that angle C is said to have 60 degrees. a right triangle has a total angle of 180 degrees. so, 180 - 90 - 60 = 30 degrees. Therefore, angle A is 30 degrees.
27. Now you want the measure of the hypotenuse, and you know this a right triangle. so, simply use the law of sines to find the measure of AC :
4cm/sin(60) = AC/Sin90
AC = 4.62 cm
29. angle z is in the other figure and same stuff, just substract the angles, you have 90 degrees and 30 degrees... 180 - 90 - 30 = 60 degrees
31. Angle Y = 90 degrees
this value is already given, it's the little square that indicates a 90 degrees angle.
26. 5 cm
28. 90 degrees
30. You already found AC, use the pythagorean theorem. sqrt((4.62)^2 - 4^2) = 2.31 cm
32. use pythagoras again, square root(5^2 - 3^2) = 4
So as you can see all the measurements are the same because if you see at the very top of your figures it says ABC = XYZ which means pretty much that they have the same values (notice that there is a little something added to the = sign, watch out for that because that's what indicates that two figures are equal in terms of angles and measures.
