well, in short, the students and chaperones are at a 2 : 9 ratio, and we know there are 171 students, how many chaperones then, so long they maintain a 2:9 ratio?
9x-7=-7 how do you solve this problem
2 answers:
Well, if we're looking for the value of "x" then follow these following steps!
Our first step: 9(x) - [-7] = ?
The "?" = 0
Our second step 2: Solve this one → 9(x) = ?
Remember that I said "?" equals to 0
Our third step: we have to divide by the number "9" on each of your sides
Our fifth step/your answer is:
Oh and if you wanted to find out how many solution that it has, it would be One Solution
There's not that much steps to this solution

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.
