Use the expression the problem gave.  Let n equal the number of CDs Jim owns.  
n=# of CDs Jim owns
5 less means subtract
2 times means multiply let Marcus = number of Marcus's CDs

Answer:

2n -5 is the expression which represents the number of CDs Marcus has

Step-by-step explanation:

Given the statement: Jim has a number (n) of CDs in his collection.

⇒ Jim has a number of CDs in his collection = n

Also, it is given that Marcus has 5 less than 2 times the number of CDs Jim has.

"2 times the number of CDs Jim has" means 2n

"5 less than 2 times the number of CDs Jim has" means 2n -5

then;

Marcus has the number of CDs = 2n -5

Therefore, the expression which represents the number of CDs Marcus has ; 2n -5

Vinil7 [7]

Answer:

3 pounds of peanuts and 2 pounds of cashews

Step-by-step explanation:

Let x be the pounds of peanuts and y be the pounds of cashews

Greta wants to make 5 pounds of a nut mix using peanuts and cashews.

So, x+y=5 ----- A

Cost of 1 pound of peanuts = $4

Cost of x pounds of peanuts = 4x

Cost of 1 pound of cashews = $9

Cost of y pounds of cashews = 9y

Her budget requires the mixture to cost her $6 per pound

So, cost of mixture of x pounds of peanuts and y pounds of cashews is 6(x+y)

So, 4x+9y=6(x+y) --- B

Plot A and B

x+y=5 ---Blue

4x+9x=6(x+y) ---Green

Refer the attached figure

Intersection point = (x,y)=(3,2)

Hence she should use 3 pounds of peanuts and 2 pounds of cashews
