n + 10
Step-by-step explanation:
Answer:
15 a. It is not a rectangle bc the sides of a rectangle are always the same.
b. It is a right triangle bc on D it is 90 degrees.
c. It is not an isosceles triangle bc an isosceles triangle's base is always even but the one in the picture is not
Step-by-step explanation:
Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.

Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.
__
2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra
