Answer:
estimated gpa: 2.85
Step-by-step explanation:
Evaluate y=0.14x+0.75 at x = 15 (hours):
y = 0.14(15 hours) + 0.75
= 2.1 + 0.75
y = 2.85 = estimated gpa corresponding to 15 houirs of study
Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area

Step-by-step explanation:
Answer:
218 adults and 104 children attended.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=322 (1)
8.75x+6y=2531.50 (2), where:
x is the number of adults
y is the number of children
First, you can solve for x in (1):
x=322-y (3)
Then, you can replace (3) in (2) and solve for y:
8.75(322-y)+6y=2531.50
2817.5-8.75y+6y=2531.50
2817.5-2531.50=8.75y-6y
286=2.75y
y=286/2.75
y=104
Finally, you can replace the value of y in (3) to find x:
x=322-104
x=218
According to this, the answer is that 218 adults and 104 children attended.
