Mary is buying tickets for a movie.
• Each adult ticket costs $9.
• Each child ticket costs $5.
• Mary spends $110 on tickets.
• Mary buys 14 total tickets.
How many adult tickets, and how many child tickets, does she buy?
Please explain your work! I will mark brainliest if you do :)

Answers

adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

adult ticket = xchild ticket = y

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

x = 10

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

y = 4

∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

Please how do we solve this? Fast

Write an expression equivalent to (9m3 + 5m2 - 3y 2) - (2m3+2m2) - (3m2 - y2) using the fewest number of possible terms

Answers

Answer: 7m³ - 2y²

Step-by-step explanation:

Answer = (9m³ + 5m² - 3y²) - (2m³+2m²) - (3m² - y²) [expand the brackets]

= 9m³ + 5m² - 3y² - 2m³- 2m²-3m² + y² [group like terms]

= 9m³- 2m³+ 5m²- 2m²- 3m²- 3y²+ y² [simplify]

= 7m³ - 2y²

7/8 - 4/5 what is the answer to this thing because i don't know it at all duhhhh

Answers

7/8-4/5. When subtracting two fractions, we must have a common denominator. A common denominator is a factor in which goes into both 8 and 5.

1.) Common factor: 45. 45 goes into and 8 and 5. If we list out all the factors of 8 and 5, 45 will be the lowest common factor.

2.) We need to multiply by a number to get 45 for each denominator. We can a one-step equation to figure out what we need to multiply 8 by and 5 by to get 45.
X=the factor of 8 that will get us 45.
8x=45
8x/8=45/8
x=5.625.
Y=factor of 5 that will get us 45.
5y=45
5y/5=45/5
y=9.

3.) We now know that we need to multiply 8 by 5.625 and 5 by 9 in order to get 45 as the denominator for both fractions.
7/8x5.625-4/5x9
7/45-4/45.

4.) Whatever is done to the denominator must be done to the numerator.
7x5.625/45-4x9/45
39.375/45-36/45

5.) We now have common denominators, so we simple subtract the numerators ONLY. We DO NOT subtract the denominators.
39.375/45-36/45=3.375/45.

Therefore, 3.375/45 is your answer.

Help! Please no links or I will report u!!

Answers

Answer:

Step-by-step explanation:

The range is all of the y values that make a function true. Our graph here starts at y=-2 and then goes up for infinity. This means the range is y ≥ -2. The domain is [0, ∞) because our x values start at 0 and go to infinity. This means the domain is restricted so A is not true, B is not true because the graph does not exist at x = -2.

Then find the common factor for both pairs

4(6x^2-2x-9x-3)

Then rewrite in factor form
