Clarice drove the same distance on each of 4 days. then, on the fifth day, she drove 48 mi more for a total of 828 miles. how many miles did she drive on each of the first 4 days?

4x+48 =828

subtract 48 from each side

4x =780

divide by 4

x=195

she drove 195 miles on each of the first 4 days

c.   x=2.4cm

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.
