Answer:
Step-by-step explanation:
We need x first.
AB = DE
12 = 3x -3
4 = x -1 . . . . . divide by 3
5 = x
Now, we can find y.
∠C = ∠F
7x +y = 55
y = 55 -7x = 55 -7(5)
y = 20
Answer:
The Science Center charge less than the Dino Discovery museum for more then 10 students
Step-by-step explanation:
Let us assume that the number of students are x .
Let us assume that the total charge for x students be y.
As given
Mrs. Williams is deciding between two field trips for her class.
The Science Center charges $120 plus $5 per student.
Than the equations becomes
y = 120 + 5x
The Dino Discovery Museum simply charges $7 per student.
y = 7x
Than





Therefore the Science Center charge less than the Dino Discovery museum for more then 10 students.
Answer: First problem: 5 2/12 + 5 4/12 = 21/2= 10 1/2
Second problem: 6 11/12 -4 8/12= 9/4=2 1/4
Step-by-step explanation:
The answer is D she started out with 250$ and then subtracted 250$
250-250=0
