Answer:
a)64
b)96
Step-by-step explanation:
For this we calculate the number of rows, 32, as 2+3 is 5, and 160/5 is 32. Then we know that there are 32 rows, and in each row are 2 left seats and 3 right seats, so we multiply 32 by both numbers for the answers.
Answer:
3x+5y=4
Step-by-step explanation:
y=-3x/5 + 4
move the 5 to the other side so:
5y=-3x+4
then move -3x to the other side so:
5y+3x=4
and that is yr answer

Answer:
an=29.7(1/3)^(n−1)
Step-by-step explanation:
The first term, a1, is 29.7.
The common ratio, r, is 9.9/29.7 = 1/3.
The generic explicit rule is ...
an = a1·r^(n-1)
Filling in the values you have gives the explicit rule ...
an = 29.7(1/3)^(n-1)
