Answer:
1.50n≤84
Step-by-step explanation:
The statement indicates that Samantha knows that she has made at most $84 in sales and this means that that is the higher amount she thinks she can have. So, the total amount could be less than that or equal to that. Also, the total amount she has would be the result of multiplying the price per ticket for the number of tickets sold. Moreover, this amount would be less than or equal to 84 and the symbol that represents less than or equal to is ≤. According to this, the inequality that would model the information is: 1.50n≤84.
Answer:
X=3
Step-by-step explanation:
1-move the (9v) to the other side and change it to negative and it will be (13v-9v=12)
2-Collect like terms and it will be (4v=12)
3-Divide both sides on 4 and it will be (v=3)

Answer: Q"(10,10) , R"(35,10), S"(35,25) , T"(10,25)
Step-by-step explanation:
Given: On the blueprint, 1/4 inch equals 1 foot in the actual house.
Therefore, 1 inch of blue print = 4 feet of room.
The coordinates of the room will be [multiply 4 to the coordinates of rectangle]
Q(2,2)→ Q'(8,8)
R(7,2)→R'(28,8)
S(7,5)→S'(28,20)
and T(2,5) →T'(8,20)
The homeowner wants this room to be 25% larger.
Let x be the dimension of current room. then the dimension of new room= x+25% of x
=x+0.25x=1.25x
So for dilate the room by 25% multiply 1.25 on the coordinates of the enlarged room , we get
Q'(8,8)→Q"(10,10)
R'(28,8)→R"(35,10)
S'(28,20)→S"(35,25)
T'(8,20)→T"(10,25)
