Answer:

Step-by-step explanation:

Additive identity is a property that involves the sum of two or more integers in an equation without compromising the equality of the equation.

Given the equation

(5+2)+n = 7+n

We can see that the right hand side of the equation is derived from the left hand had by addition of the values in parenthesis.

Given the right hand side;

= 5+2+n

= (5+2)+n

adding the expression in parenthesis will give;

= 7 + n

Since we added the expression in parenthesis to arrive at the expression at the right hand side, hence additive identity was used in the calculation.

How do you graph y=3x^2

Rainbow [258]

So because it's x^2 that means it's a parabola. The 3 before it is it's stretch factor (slope, so instead of going over one up one it goes over one up 3)

Tan(Θ)=(h/distance from base)
Θ=13 degrees, 1mile=5280 ft
tan(13)=(h/5280 ft)
5280tan(13)=h
h=1218.984049
h=1219 ft

The drama club is printing t-shirts for its members. The printing company charges a certain amount for each shirt plus a setup f

Helga [31]

The cost of each t-shirt is $7, using the equation formed from the given conditions.

In the question, we are given that the drama club is printing t-shirts for its members. The printing company charges a certain amount for each shirt plus a setup fee of $40.

We are aske to find the cost of each t-shirt if there are 21 students in the club and the t-shirt order costs a total of $187.

We assume the cost of one t-shirt to be $x.

Thus, the cost of printing 21 t-shirts = $21x.

The setup fee is given to be $40.

Thus, the total cost of printing 21 t-shirts for the dram club = $21x + 40.

But, we are given that the total cost is $187.

Thus, we get an equation,

21x + 40 = 187.

This equation can be solved as follows:

21x + 40 = 187,

or, 21x = 187 - 40,

or, 21x = 147,

or, x = 147/21,

or, x = 7.

Thus, the cost of each t-shirt is $7, using the equation formed from the given conditions.
