Answer:
B) x +20 is greater than or less to 45
Step-by-step explanation:
One way is to trace around one of the triangles and place it over the other. If<span> the angles and sides match exactly, then the </span>two<span> are </span>congruent<span>. But there is another way to </span>tell<span>. </span>If two<span> triangles have </span>congruent<span> corresponding parts, then the triangles are </span>congruent<span> triangles.

a.) 1/2n 4=3−5/n b.) 1/2(n 4)=5/n−3 c.) 1/2(n 4)=3−5/n d.) 1/2n 4=5/n−3
Let's assume the number be n.
So, sum of number and four can be written as n+4.
Now one-half of n+4 will be
.
Quotient of five and the number can be written as
.
Now three less \frac{5}{n} can be written as \frac{5}{n} -3.
So, one-half the sum of a number and four is three less than the quotient of five and the number can be converted into equation as follows:

So, b is the correct choice.
Answer: The answer would be (7,-3)
