Answer:
a=14
Step-by-step explanation:
I only have the answer for A.
Step 1: What we need to do is divide 91 by 13: 91/13=7
Step 2: Multiply 7 by 2 becasue there were 2 members in the beginning. 7*2=14
There you have your answer: a=14
It will need 14 team members to solve 91 problems in 1 hour.
It will need 30 team members to solve 91 problems in 1 hour.
Given that,
Two members of the Math Competition Team solve 13 problems in 1 hour. Assume all team members solve problems at the same rate.
We have to determine,
How many team members are needed to solve in 1 hour: 91 problems.
How many team members are needed to solve in 1 hour: 195 problems.
According to the question,
- To solve in 1 hour: 91 problems team members are needed = Two members team solve 13 problems in 1 hour.
Then,
[tex]\dfrac{91}{13}= 7 \ problems\ per \ 2 \ members[/tex]
Two member per 7 problems = (7).(2) = 14
It will need 14 team members to solve 91 problems in 1 hour.
- To solve in 1 hour: 195 problems team members are needed = Two members Team solve 13 problems in 1 hour.
Then,
[tex]\dfrac{195}{13}= 15 \ problems\ per \ 2 \ members[/tex]
Two member per 15 problems = (15).(2) = 30
It will need 30 team members to solve 195 problems in 1 hour.
