It would be using PEMDAS, "Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction" 

Since 4 x 5 is in parenthesis, you solve that first: (4x5)-3 => (20)-3 

Then subtract: 20-3 = 17

If you solve using the order of operations, you will get 17.

considering the one time deposit and monthly went rent the equation y equals 1200+400x can be used to represent why the total co
Ilia_Sergeevich [38]

The trick with this problem is that there is no trick - there's no math involved at all, just wordplay. The key is in one-time deposit; what you're looking for isn't a recurring fee, but rather a constant. Now, an equation is made up of three things:

  • a variable
  • a relational statement in the form of =
  • a constant, even if it isn't really there, it's zero

In this case, what you're looking for is the constant in the equation; a value that doesn't change when any variable changes.

The only number in your question that fits the bill is 1200$, since it's a <em>one-time, unchanging value.</em> <em>y </em>is the total amount paid and x represents the months, which are both variables; 400 is tied to x, so it also changes based on months.

What is the area of the following shape?
kotegsom [21]

Answer:

104 m^2

Step-by-step explanation:

We first find the area of the rectangle

A = l*w

A = 10*8

A = 80

Then we find the area of the triangle

A = 1/2 bh

A = 1/2 (8)(6)

   = 24

Then we add the areas together to find the total area

80+24 = 104

Crazy boy [7]
I think the possible way that the percentage vote of a country is different to the next random sampling to the other data table is its population in each country. In the first table i think Malta has the edge to this table data and place in number 1 but to the other data table the country was left of.
