Hiro and his co-workers had lunch at a restaurant near their work. An 18% tip on their bill was $10.08. How much was the bill, n
Ghella [55]

Answer:

$8.27

Step-by-step explanation:

First we need to find the tip.  We know it was 18% of the total. So...

x (the variable we need to find)         18%

__                                                   =     ___

10.08 (the total bill including tip)        100%

cross multiply

100x = 181.44

--------------------   (divide by 100 to get x by itself)

100

x = 1.81 (The 18% tip that was given)

So now we know how much the tip was, we subtract it from the bill

10.08 - 1.81 = $8.27

Find the slope and reduce.<br> P=(-8, 3) Q=(-6, 2)<br> Slope
Lyrx [107]

Answer:

-\frac{1}{2}

Step-by-step explanation:

Slope/Gradient = \frac{y1-y2}{x1-x2}

P = (-8 , 3) (x1, y1)

Q = (-6 , 2) (x2, y2)

Slope = \frac{3-2}{-8-(-6)} =\frac{1}{-8+6} = \frac{1}{-2} = -\frac{1}{2}

Solve for x - Pre algebra
aniked [119]
In this case you would set it up as
6x + 4x + 130 = 180
(180 represents the degree of the triangle)

Add up like terms
10x + 130 = 180
Subtract 130 to the other side (180-130)

10x = 50
Divide 10 to the other side ( 50/10)
.
x = 5
Hope this was clear :)
