Answer:
a = 
x = 27y
Step-by-step explanation:
Order of Operations: BPEMDAS
<u>Question 1</u>
Step 1: Write out discriminant
d = b² - 4ac
Step 2: Subtract b² on both sides
d - b² = -4ac
Step 3: Divide both sides by -1
b² - d = 4ac
Step 4: Divide both sides by 4c
a =
<u>Question 2</u>
Step 1: Write out equation
2/3(x - 18y) = 6y
Step 2: Distribute parenthesis
2/3x - 12y = 6y
Step 3: Isolate <em>x </em>by adding 12y on both sides
2/3x = 18y
Step 4: Divide both sides by 2/3
x = 27y
8 I don’t know how to explain but the answer is
8
If it was bought after 10% discount, it means it was bought at 90% of the original price:
90% = $450
1% = $5
100% = $5 x 100
100% = $500
The original price of the Play Station was $500.
Answer:
1, 2, 2, 2, 3, 8, 9
Step-by-step explanation:
The following data represent the times in minutes required for 18 co-workers to commute to work
48 42 31 29 41 22 38 38 21 39 22 48 22 12 34 32 23 28
Rewrite this data in ascending order
12 21 22 22 22 23 28 29 31 32 34 38 38 39 41 42 48 48
Now, the stem-and-leaf plot is
The second row represents the leaves for the given data points in the range 20 to 29 for this stem-and-leaf plot, so the answer is
1, 2, 2, 2, 3, 8, 9
4. angle H is congruent to angle B
5. GH/DJ = AB/DC
