use the following information to find your course average in amdm, if homework is weighted 20%, class participation is 25%, test grades are 30%, and final exam is 25%.
 homework {90, 94, 96, 90}
 class participation {95, 99}
 test grades {87, 75, 82 ,85}
final exam grade {71}
18.5 + 24.25 + 24.675 + 17.75
a. 85
b. 88.5
c. 87
d. 89

a is the answer

Step-by-step explanation:

work is pictured and shown

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
