Elvira is keeping track of the number of students who choose to buy their lunch in the cafeteria. • 4 equal-sized classes enter the cafeteria at the beginning of lunch.
•Five more students arrive late to lunch.
•The students then divide into three equal lines.
•Elvira notices that each of the lunch lines serve 31 students.

Write and solve an equation to find the number of students in each class.

(⚠️Need answer urgently)

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.

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

i don't think there is enough
