Answer:
55 square feet jsjjjis the answer
8 = 2^x + 4
2^x = 8 - 4
2^x = 4
as you know 4 = 2^2 so now you have:
2^x = 2^2
x = 2
100+x (s)+68.25(t)=a
S=shirts
T=trophies
A=amount paid
Yes because each output (y) has a unique input (x).
1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is

of 12 (hours)
The opposite of

is 2
6 (hours) multiplied by 2 (opposite of

) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours
