Answer:
Step-by-step explanation:
An baseball player’s batting average decreases from 0.312 to 0.278 .
Let be the initial baseball player’s batting average and be the final baseball player’s batting average .
Initial value = 0.312
Final value = 0.278
So, change in value =Final value - Initial value = =
Therefore , decrease in value = 0.034
We know that percent decreased = ( decrease in value × 100 ) ÷ Initial value
i.e. ,
Or we can say percentage change in baseball player’s batting average =
First you have to change y to x
X= 2y+5/2
Then find y
(X-5/2)/2=y
So (X-5/2)/2 is the. Inverse function
300 cookies were ordered to start.
We can tell this because we know 12% is equal to 36. Because this is true, we can set up a proportion to solve. All proportions can be set up with the small number on top and the total on the bottom. This will help you solve for the missing number, which is in this case the total number of cookies. Let x be the total number of cookies.
Percentage/total percentage = cookies/cookies total
12/100 = 36/x
Now we can cross multiply to solve.
(100)(36) = (12)(x) ----> multiply
3600 = 12x ---> divide by 12
300 = x
Answer:
y= 3x + 5
Step-by-step explanation:
The +5 represents the starting 5 action figures, and the 3x represents the 3 action figures he collects each month.
Answer:
$7.43
Step-by-step explanation:
First, solve for what each of the 5 friends are paying:
130/5 = 26
Then, solve for what each person is paying with the addition of 2 people:
130/7 = 18.57
Last, subtract to find the answer:
26-18.57 = 7.43
