Answer:Julie's average score was 76
Step-by-step explanation:
The formula for Average or mean is expressed as
Average = sum of terms / total number of terms.
Julie's first three test scores in biology were 65, 90 and 73.
The sum of the scores would be
65 + 90 + 73 = 228
The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,
Average = 228/3 = 76
Answer:
Willhem
Step-by-step explanation:
The given equation is
Step 1 : Add 32g and 8g.
Step 2: Subtract 10 from 40.
Step 3: Divide both sides by 30, find the value of g.
The value of g is 5.
Therefore, Wilhem is correct.
Answer:
x = 8, y = 3
Step-by-step explanation:
Equating corresponding x and y coordinates , then
- y = - x + 5 ( multiply through by - 1 )
y = x - 5 → (1)
2x - 5y = 1 → (2)
Substitute y = x - 5 into (2)
2x - 5(x - 5) = 1 ← distribute and simplify left side
2x - 5x + 25 = 1
- 3x + 25 = 1 ( subtract 25 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Substitute x = 8 into (1) for corresponding value of y
y = 8 - 5 = 3
