1. Donald scored 76%, 79%, 84%, and 87% on his four geometry tests this semester. There is one test remaining. Donald's homework average is 93%. His teacher will count each test score and the
homework average as one-sixth of Donald's final grade.
a. Write an equation to determine the score that Donald must attain on his last test to have a
final grade of exactly 85%.
b. Solve the equation and justify the answer by showing your work.
c. Write a sentence explaining what your answer means.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
