so i tried this the first time and got it wrong and now im on my last attempt and im even more confused. Please help and explain in detail! I cant learn anything if you just tell me the answer without going in detail and breaking down the problem.

I think 55 is the answer

Step-by-step explanation:

6x - 5 (x = 10)

=6(10) - 5

=60 - 5

=55

In algebra if a variable is right beside a number then the number is multiplied by the variable for example 6x - 5, in this case x = 10 so 6 x 10 = 60. Then the next part is subtraction so

60 - 5 = 55. Therefore 55 is the answer.

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.
