Represent this statement as an equation: The difference of twice a number and 3 is 11.
Answers
Answer:
2x - 3 = 11
Step-by-step explanation:
"difference" means subtraction, so it is subtraction.
"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.
"Is 11" just means equals 11.
so, 2x - 3 = 11.

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.
Answers
Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9

if the fraction 396/x-10 is equivalent to -22, find the value of x.
Answers
Answer: x = -8
Step-by-step explanation:
1. Miltiply x-10 on both sides: 396 = -22(x - 10)
2. Distribute -22 to (x - 10): 396 = -22x + 220
3. Subtract 220 from 396: 176 = -22x
4. Divide both sides by -22 to get x by itself: x = -8
