Answer:
?=19
x=30
Step-by-step explanation:
5/6x - 1/5x = 19
5(5/6x) - 6(1/5x) = 19
25/30x-6/30x=19
19/30x=19
19x=19(30)
19x=570
x= 570/19
x=30
To make the sure the results did not happen by chance, the coach can ensure that the protein bars are the only difference between the two groups. For example, he can make sure that both groups are drinking the same amounts of water and getting in the same amount of practice; that way, he will be able to determine that one group is performing better due to the protein bars only. Also, the coach can repeat this experiment multiple times to make sure that the results weren't a random, one-time thing.

Answer:the equation is 200 + 10x
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount deposited into the account.
R represents interest rate on the principal
T represents time in years
I = interest after t years
From the information given
T = x years
P = $200
R = 5%
Therefore
I = (200 × 5 × x)/100
I = 1000x/100
I = 10x
Therefore, the equation representing the total amount of money that would be in the account after x years would be
200 + 10x
