Answer:this one is hard
Step-by-step explanation:
From 100 to 80 is 8/10, so the recursive formula is
an=a(n-1)*1/8
or
an= a1*1/8(n-1)
an=a1*(n-1)/8
There are 3 because 12 divided by 4 is 3.
Answer:
n+4=32
Step-by-step explanation:
The initial number n gets additional 4 students making the new total number of students to be 32. Therefore, this situation can be represented as
n+4=32
To get the actual number of students before the additio, we make n the subject of formula hence
n=32-4
n=28
Therefore, the initial number was 28 and the equation is n+4=32
Since no choices were provided, the equation that can be modified is n+4=32
Joe : x
jim : y
x+y=16
y=1.50+x
x + 1.50 + x = 16
2x = 14.5
x = 7.25
7.25 + y = 16
y= 8.75
Joe : $7.25
Jim : $8.75
