Answer:
The answer is 457
Step-by-step explanation:
You set up an equation as
10a+7c=6459
a+c=783
c= child
a= adult
then you simplify to 3a=978 by taking out one of the values. You get a - 326.
783-326=457 so there is your answer
9.3 × 107 would be the scientific notation

y = 7 + 3/5
y = 35/5 + 3/5
y = 38/5
y = 2*(38/5)
y = 76/10

lunch time:
z = 1/2
z = 5*(1/2)
z = 5/10
---
time switching classes:
w = 7/10
---
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (76/10 - 5/10 - 7/10)/6
x = (76 - 5 - 7)/(10*6)
x = (64)/(10*6)
x = (2*2*2*2*2*2)/(2*5*2*3)
x = (2*2*2*2)/(5*3)
x = 16/15
x = 1.0666666666

check:
y = 7 + 3/5
y = 7.6
z = 1/2
z = 0.5
w = 7/10
w = 0.7
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (7.6 - 0.5 - 0.7)/6
x = 1.0666666666

Answer: The volume of the apartment is 2,160 ft3.
An hourly rating of 2.5 BTUs per cubic foot is required, so multiply the total volume by 2.5.
Arthur needs an air conditioner that will provide 5,400 BTUs to properly cool his apartment
