Answer:
|x−10|=5
The maximum and minimum time(x) gets subtracted by 10 resulting in the 5 minute time vary.
Answer: Yes this is a right triangle
We can determine this by using the converse of the pythagorean theorem.
a = 5, b = 12, c = 13

Since those a,b,c values work in the pythagorean theorem, this proves we have a right triangle.
Answer:
use the distributive property
Step-by-step explanation:
Use the distributive property to rewrite the expression with the GCF factored out.
<u>Example</u>:
ab +ac +ad . . . . has terms with a common factor of 'a'
When the common factor is factored out, the distributive property tells you the equivalent is ...
= a(b +c +d)
If 'a' is the greatest common factor, then b, c, d are mutually prime and no more factors can be removed to outside the parentheses.
Answer: Option C
, 
Step-by-step explanation:
If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.
By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a', b', c' then:

In this case

So:

Now solve the equation for the variable y



We know that
and 
Then


Finally the answer is:
, 
The first number is 16 and the second is 18
System:
x + y = 34
(1/2)x + (1/3)y = 14
