Step-by-step explanation:
let Sean be 4 years old and Rachel be 2 years old on April 17
part (A)
R=S-2 --(A)
is an equation that can be used to determine Rachel's age
likewise,
S=R+2--(B)
can be used to determine Sean's age
part (B)
use equation(A) for table (1) and equation(B) for table 2
Table (1) : R=S-2=11-2= R=9
12-2=10=»R=10
13-2=11=»R=11
14-2=12=»R=12
15-2=13=»R=13
16-2=15=»R=14
likewise use equation B for the table (2)
the outputs must be 3,4,5,6,7,8
and 9
No it isn't because it wasn't an expression. An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)
Billy can do 4 hours which is 1000 pictures
and Sandy 3 1/15 hours 500 pictures and 1/15 is 50.

Hope this helps
It should be A and D, no promises
