So what we're dealing with here is a similar triangle situation. Since ML is a midsegment, that means that IL and LJ are congruent. So, IL=LJ=13. This means that the whole side IJ is 26 (13+13=26). We also know that triangle IML and triangle IKJ are similar triangles, so their sides are proportional. This means that we can set up the ratio:
12/13 = x/26
and solve for x.
After multiplying 26 to both sides of the equation, we find that x=24, so KJ=24.
A because the square is in the (10) place and the circle is in the (1) place and 10 is 10 times bigger than 1
To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:
Answer: x= 2.5, y = 10
Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:
And cross-multiply:
Then solved for x and y:
Answer: seven-teen
Step-by-step explanation:twenty minus three
