Answer:
3h = 19.50
Step-by-step explanation:
First lets define the price of each hat as the variable h.
Next we know that there are 3 hats so we can write that variable as 3h
We also know that the cost of all 3 hats was $19.50. This means that we can set each side of this equation equal to each other.
This gives us the equation 3h = 19.50
If you were to solve for h, you would get
Which would simplify to
h = 6.50
This means that each hat costs $6.50
<u>Ratio of two angles are 6:13.</u>
So, let the one angle be and another be
As we know that,
Sum of all interior angles of a quadrilateral =
So let's sum up the given angles,
Hence,
So, First angle
Second angle

Answer:
D
Step-by-step explanation:
The expression is
We can follow the rule of "PEMDAS" here.
PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract
So, we first need to deal with Parenthesis. Next,
There aren't any exponents, so we deal with Multiplication of 7 and 3.
Then addition/subtraction.
Hence, the first step, from the answer choices, would be D, multiply 7 and 3
