Beth needs to add a 15% tip to her $12 meal. How much total money does she need?

$13.8

Step-by-step explanation:

15% of 12 is 1.8, so if you are adding 15%, that would make the equation

12 + 1.8 = 13.8

$13.80

Step-by-step explanation:

Let's first figure out how much the tax is in dollars.

We see that Beth will be tipping a value of 15% of her $12 meal. Remember that in math, "of" almost always means to multiply, so we're multiplying 15% by 12:

15% * 12 = 15/100 * 12 = 0.15 * 12 = $1.80

So, the tip is $1.80. Add this to the original $12 to get the total cost:

$1.80 + $12 = $13.80

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

slope is 35 and 20 miles is the y-intercept.
