Answer:
y — x = 5
5y — x = 353
Step-by-step explanation:
Let the fifth score be x
Let the average of all the scores be y.
But the fifth score is 5 points lower than the average ie
y — x = 5 (1)
The average of the scores is the sum of all the scores divided the number of scores. This is written as
y = (85 + 92 + 82 + 94 + x) /5
y = (353 + x) /5
Multiply through by 5
5y = 353 + x
Rearrange the equation
5y — x = 353 (2)
The equation Markus will use to determine the x is given as
y — x = 5
5y — x = 353
Surface area of this triangular prism is
Area of 2 congruent triangles + Area of rectangle(6*2) + Area of rectangle(2*4) + + Area of rectangle (2*3)
Area of triangle = 1/2*6*2 =6 in²
Surface area of this triangular prism = 2*6 +6*2 +2*4 +2*3= 12+12+8+6= 38 in²
Answer is 38 in².
