Luda [366]
If $26 represents the cost of  the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.


The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.

26+4(6-5)
26+4(1)

Hiii dont mind the answer that i put but im not sure if im right, can someone please help me?
AVprozaik [17]

Answer:

Option 4

Step-by-step explanation:

The volume of a cylinder is going to be the area of the base (which is a circle) times the height. if you have cylindrical mug, then you can use the base area×height relationship, but it won't be exact because some of the volume is going to be used for the walls of the mug itself.

Anyways:

Volume = Base Area × Height

•Base Area -> Circle = π×radius²

•Height is given as 7in.

Volume = π×(6.2in)² × 7in = 845.33975...

Volume is in units cubed (the 3rd power) which is where the in³ is from. Your closest option here looks to be the 4th choice.

Joan took her three children to the zoo. Admission is $7 each. The snack bar sells water for $2 per bottle and chips for $3 per
lys-0071 [83]

The expression for the total cost of their trip is 7 + 2x + 3y.

As per the question, assuming the number of bottles to be x and number of bags to be y. The equation will have one time fee of admission, product of cost of bottles and number of bottles and product of cost of bags and number of chips bags.

The one time fee and two products will be added to form the expression. Forming the equation now -

Expression = 7 + 2x + 3y

Therefore, the expression of trip when x bottles of water were bought during the visit is 7 + 2x + 3y.
