Answer: He watched 9 episodes over winter break.
Step-by-step explanation:
Given: Total episodes watched = 45
After school started , he watched 9 episodes per week.
So in 4 weeks. he watched = 9 x 4 = 36 episodes.
Number of episodes he watched over winter break = 45-36
i.e. Number of episodes he watched over winter break = 9
Hence, he watched 9 episodes over winter break.

Answer:
b=4/3
Step-by-step explanation:
Distribute first
6b - 15 = 4 - 3b - 7
6b - 15 = -3b -3, add 3b to both sides
9b - 15 = -3, add 15 to both sides
9b = 12, divide both sides by 9
b = 12/9 = 4/3
Answer:
The probability is that he hits 5.6 out of 7 attempts.
Step-by-step explanation:
Given that an archer hits his target 80% of the time, if he shoots 7 arrows, to determine what is the probability of each event, the following calculation must be performed:
7 x 80/100 = X
560/100 = X
5.6 = X
Therefore, the probability is that he hits 5.6 out of 7 attempts.
He invested two unknown amount that add to $1200.
Let the amount invested at 9% be x.
Let the amount invested at 3% be y.
The amounts add to $1200.
x + y = 1200 First Equation
The profit from the 9% part is 0.09x.
The profit from the 3% part is 0.03y.
The two profits add to $78.
0.09x + 0.03y = 78 Second Equation
We have two equations in two unknowns, so we can solve this problem as a system of equations.
x + y = 1200
0.09x + 0.03y = 78
Multiply the first equation by -0.09 and add to the second equation.
-0.09x - 0.09y = -108
0.09x + 0.03y = 78
----------------------------
-0.06y = -30
Divide both sides by -0.06
y = 500
Now we substitute 500 into y in the first equation.
x + y = 1200
x + 500 = 1200
x = 700
Answer: The amount invested at 9% is $700
