If they are in right side then we use (+) plus sign in power.

At Southwest HS, the number of student in band is 1 3/4 times the number in orchestra. If 56 students are in orchestra, how many are in band?

Answers

It is important to take note of all the information's that are given in the question. It would be easy to solve the problem based on the information's given in the question.
Number of students in orchestra = 56
The number of students in band is = 1 3/4 times that are in orchestra
Then
Total number of students in band = (7/4) * 56
= 7 * 14
= 98
So 98 students are there playing in the band. I hope the answer and the procedure is clear to you. In future you can use this procedure to solve similar kind of problems without requiring any help from outside.

56 students* (1 3/4)= 98 students.

There are 98 students in the band~

Write equivalent expressions for each:
A. 2X+5X+7-3
B. 4X-2Y=10X
C. 2P+12+2P-8

Answers

A. 2X+5X+7-3
= (2X+5X)+ (7-3) (combine like terms)
= 7X+ 4

B. 4X-2Y+10X
= (4X+ 10X) -2Y (combine like terms)
= 14X -2Y

C. 2P+12+2P-8
= (2P+ 2P)+ (12-8) (combine like terms)
= 4P+ 4

Final answer:
A. 7X+4
B. 14X -2Y
C. 4P+ 4

Hope this helps~

A.
2x + 5x + 7 - 3
(2+5)x + (7-3)
7x + 4

B.
4x - 2y + 10x
4x + 10x - 2y
(4+10)x - 2y
14x - 2y

C.
2p + 12 + 2p - 8
2p + 2p + 12 - 8
(2+2)p + (12-8)
4p + 4

A game has 3 possible outcomes, with probabilities p1, p2, and p3. The amount of money that you will win or lose for each outcome is v1, v2, and v3, respectively. What is the expression p1v1 + p2v2 + p3v3 equal to?

Answers

We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3

Therefore,
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.

Answer:

Option b) The average amount you will win (or lose) per game in the long run
