Answer:
Step-by-step explanation:
These types of equations are called simultaneous equations and the method we can use to solve these type of equations is either Substitution, Elimination and Graphing.
We use substitution here because it is easier.
Equation 1
Equation 2
Lets take equation 1
This is our equation 3 , now put it inside equation 2.
We found the value of y , now to find the value of x insert the value of y in equation 3
Solved ! See the attached image on both the straight line graphs i have attached for better understanding. Where both the lines intersect each other is our value of (x , y) respectively.
We need to find the expression for " number_of_prizes is divisible number_of_participants". Also there should not remain any remainder left. On in order words, we can say the reaminder we get after division is 0.
Let us assume number of Prizes are = p and
Number of participants = n.
If we divide number of Prizes by number of participants and there will be not remainder then there would be some quotient remaining and that quotent would be a whole number.
Let us assume that quotent is taken by q.
So, we can setup an expression now.
Let us rephrase the statement .
" Number of Prizes ÷ Number of participants = quotient".
p ÷ n = q.
In fraction form we can write
p/n =q ; n ≠ 0.

Answer:
inverse operations is with oppisite operations that undo each other.
open circle is circle not filled in to show that the point is a border value and is not included as part of the solution set.
like terms is terms that have the same varible raised to the same exponent.
ordered pair is a group of two numbers written in the form (x, y) where the x value represents a horizontal position.
the last one numeric expressions is an expression involving only constants
Step-by-step explanation:
Answer:
Blair chosen to purchase shirt from company B. Given:
Each shirt costs 3.10$
Shipping cost is 4% (0.04) of total order.
=>Total cost without shipping: 150 x 3.10 = 465$
=> Total cost with 4% of shipping: 465 + 465 x 0.04 = 483.6$
=> Total cost Blair paid for one shirt: C = 483.6/150 = 3.22$
The markup is 75% of original cost:
=> Blair can multiply the total cost for one shirt by 0.75
Blair will sell shirt with price which is equal to the sum of total cost for one shirt and markup:
=> P = 3.22 + 3.22 x 0.75 = 5.64$
Hope this helps!
:)
