8.) Jim eats (r) apples and Maria eats 3 times as
many apples as Jim. Together, Jim and Maria eat
96 apples. Write an equation for this situation and
solve to find how many apples Jim and Maria eat.
Please help there are 3 answers to this question

Step-by-step explanation:

if Jim eats r apples and Maria eats 3times as Jim then we can represent the number of times Maria eats as 3r

Together, the both eat 96 apples that is:

r + 3r = 96 apples - this is the equation for this situation.

Solving further

r + 3r = 96apples

4r = 96 apples (divide through the equation by 4)

4/4 r = 96/4 apples

Then

r = 24 apples

Which means that Jim eats 24 apples while Maria eats 3 * 24 apples = 72 apples.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
