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
Answer:
A. 5/2
Step-by-step explanation:
Can't be c or d since those are negative and b would have a much steeper slope rise over run is how you find side the two points connect by going up 5 and over 2
Let width = x then
2x+ 2(x + 2) = 80
4x + 4 = 80
4x = 76
x = 19
so the width is 19 and the length is 21 answer
Answer:
2g/mL^3
Step-by-step explanation:
To find density, we use mass/volume. 40g is the mass and 20mL is the volume. 40/20 is 2, therefore, 2g/mL^3
78,000 rounded to the nearest ten thousand is 80,000.
