Answer:6:15
Step-by-step explanation:
Objective: Solve 3y - 20 = 8y for y.
Step 1: Collect the y-terms.
To collect the y-terms, you'll need to subtract 3y from both sides.
3y - 20 - 3y = 8y - 3y
-20 = 5y
Step 2: Isolate y.
Now that there is only one variable term, you must isolate the variable by dividing the term by the coefficient of the variable.
-20 ÷ 5 = 5y ÷ 5
-4 = y
Answer:
y = -4
Answer:
1st markdown = $324
2nd markdown = $259.20
Step-by-step explanation:
current price = 360
1st 6 months = 10% down
= 90% of 360
= <u>324</u>
2nd 6 month = 20% down of first 6 month
= 20% down of 324
= 80% of 324
= <u>259.20</u>
First add all the numbers in the data:
15.8 + 14.9 + 16.7 + 17.6 + 13.4 = 78.4
Divide by how many numbers are in the data set there is 5 so:
78.4 ÷ 5 = 15.7
The mean is 15.7
