What is the correct answer for both?
Answer:
15) C (3, -4)
16) B (-1, 1)
Step-by-step explanation:
8x + 6y = 0
8x + 2y = 16
8x + 2y = 16
8x = 16 - 2y
x = 2 - 1/4y
8x + 6y = 0
8(2 - 1/4y) + 6y = 0
16 - 2y + 6y = 0
16 + 4y = 0
4y = -16
y = -4
8x + 2y = 16
8x + 2(-4) = 16
8x - 8 = 16
8x = 24
x = 3
________________
-20x - 3y = 17
10x - 4y = -14
-20x - 3y = 17
-20x = 17 + 3y
x = -17/20 - 3/20y
10x - 4y = -14
10(-17/20 - 3/20y) - 4y = -14
-8.5 - 1.5y - 4y = -14
-8.5 - 5.5y = -14
-5.5y = -5.5
y = 1
-20x - 3y = 17
-20x - 3(1) = 17
-20x - 3 = 17
-20x = 20
x = -1
the cost (in dollars) of making n birthday cakes is represented by C= 24n + 35. How many birthday cakes are made when the cost is $419?
Answer:
n= 16
Step-by-step explanation:
Answer:
Step-by-step explanation:
419 = 24n + 35
419 - 35 = 24n
384 = 24n
384/24 = n
16 = n
Therefore, n = 16
Joseph ran LaTeX: 2\frac{3}{4}2 3 4 miles in LaTeX: \frac{2}{5}2 5 of an hour. How fast did Lin run in 1 hour? (try to leave your answer in a fraction) Nathaniel ran LaTeX: 8\frac{2}{3}8 2 3 miles in LaTeX: \frac{4}{3}4 3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction) Who ran the fastest, Nathaniel or Joseph?
Answer:
Nathaniel ran fastest
Step-by-step explanation:
For Joseph
Joseph ran 2 3/4 miles 2 /5 of an hour.
Speed = Distance/Time
Speed = 2 3/4 miles ÷ 2/5 hour
= 11/4 ÷ 2/5
= 11/4 × 5/2
= 55/8 miles/hour or 6.875 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
2/5 hour = 55/8 miles per hour
1 hour = x
Cross Multiply
x = 55/8 ÷ 2/5
x = 55/8 × 5/2
x = 275/16 miles per hour
x = 17 3/16 miles per hour
Nathaniel ran LaTeX: 8 2/3 miles in 4 /3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction)
Speed = Distance/Time
Speed = 8 2/3 miles ÷ 4/3hour
= 26/3 ÷ 4/3
= 26/3 × 3/4
= 26/4 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
4/3 hour = 26/4miles per hour
1 hour = x
Cross Multiply
x = 26/4 ÷ 4/3
x = 26/4 × 3/4
x = 78/16 miles per hour
x = 4 14/16 miles per hour
= 4 7/8 miles per hour
Who ran the fastest, Nathaniel or Joseph?
Hence, from the calculation above, Nathaniel ran fastest

Step-by-step explanation:
You and your mom enter a drawing with 3 different prizes. The prizes are
awarded at random.
If a total of 10 people entered the drawing, in how many ways can you win
first prize and your mom win second prize?
a. 8
b. 2
c. 10
d. 1
Answer:
The correct answer is 8.
Step-by-step explanation:
There are 2 ways that you can win first prize and your mom can win the second prize.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.
