Answer:
x = 2
Step-by-step explanation:
4 - (x + 2) - 7 = x - 9
4 - x - 2 - 7 = x - 9
-5 = 2x - 9
4 = 2x
x = 2
Please don't report me if I am wrong :(
x=2!
I think you asked: Solve for x: 4 − (x + 2) −7
The answer is x=2
Let's simplify step-by-step.
4−(x+2)−7
=4+−x+−2+−7
Combine Like Terms:
=4+−x+−2+−7
=(−x)+(4+−2+−7)
=−x+−5
That is the simplified answer. If you think carefully, I think x=2

Consider the functions f(x) = 2x + 9 and g(x) = (x - 9)/2. Calculate the following.
A. g( f( 15)) B. g( f( -3)) C. g( f( x))
9514 1404 393
Answer:
A. 15
B. -3
C. x
Step-by-step explanation:
C. Since we want different values of g(f(x)), it is convenient to find that first.
g(f(x)) = g(2x +9) = ((2x +9) -9)/2 = 2x/2
g(f(x)) = x
__
A. g(f(15)) = 15
__
B. g(f(-3)) = -3
I am selling 900 yearbooks, making a total of $2820. The large yearbook pages cost $4 and the small cost $2.50. Find how many of each I sold. HELPPP PLS
Answer:
number of large year book sold = 380
number of small year book sold =520
Step-by-step explanation:
Let the no. of large year book pages be x
given that
cost of 1 large year book = $4
cost of x large year book = x*cost of 1 large year book = $4x
Let the no. of small year book pages be y
given that
cost of 1 small year book = $2.5
cost of y small year book = y*cost of 1 large year book = $2.5y
also,
total year books sold were 900
no. of small year book + no. of small year book = 900
x + y = 900
y = 900 - x ------------------>1
also total money made by selling large and small year book = $2820
cost of x small year book + cost of x large year book = 2820
4x + 2.5y = 2820
using y = 900 - x in above equation
4x + 2.5(900-x) = 2820
4x + 2250 - 2.5x = 2820
1.5x = 2820-2250 = 570
x = 570/1.5 = 380
Thus,
number of large year book sold = 380
number of small year book sold = 900-380 = 520

~you're welcome~Tickets to a 3D movie cost $12.50 for adults and $8.50 for children. The theater can seat up to 180 people. A total of $1826 was collected in ticket sales for the sold out 7:15 PM show. Determine the number of adult tickets and the number of children’s tickets that were sold.
Answer:
74 adult tickets and 106 children tickets
Step-by-step explanation:
let x be the number of adults tickets sold out
and y the number of chlidrens tickets that sold out for the 7:15 pm show
The equations that determine our problem are
x+y=180
12.50x+8.50y=1826
lets separate x from first equation x=180-y and replace at the second equation
12.50(180-y)+8.50y=1826
12.50*180-12.50y+8.50y=1826
2250-4y=1826
4y=2250-1826
y=424/4=106
so x=180-y=180-106=74

1. The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.
(c) Explain your answer to Part 1b.

Write in slope-intercept form the equation of a line that is perpendicular to Line A and passes through the point, (4," 1"). Show your work.
Answer:
a) x = 25 tickets
y = 43.75 - Total cost
a = admission cost
b/c) 1.25(25)+a=43.75
31.25+a=43.75
43.75-31.25=12.50 cost of admission
12.50+31.25=43.75 total cost at the country fair.
(8,9) and (-2,4)
equation would be y = 1/2x+5

The total cost, y, for Leah and x friends to go to an amusement park can be modeled by a linear function. The amusement park charges an entrance fee of $45.25 per person and a parking fee of $10 per car. Leah's car has seating for a maximum of 6 people.
What is the domain of the function for this situation?
45x6=270.270 is the total for the friends.However instead you have to do 45x7=315.Because its Leahs friends and LEAH.So now the car.315+10=325.So your answer is 325

If a=6 b=24 what is ab
Answer:
144
Step-by-step explanation:
Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.
Hope this helps and good luck!!
When a = 6 and b = 24, the value of the equation ab will be 144.
What is Algebra?Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.
Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.
The expression is given below.
⇒ ab
If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,
⇒ a × b
⇒ 6 × 24
⇒ 144
When a = 6 and b = 24, the value of the equation ab will be 144.

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?
Square root of 5
Square root of 7
5
7
Answer:
7
Step-by-step explanation:
let the other leg be x
Then using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 3² = 4²
x² + 9 = 16 ( subtract 9 from both sides )
x² = 7 ( take the square root of both sides )
x = 7
Answer:
7
Step-by-step explanation:
let the other leg be x
Then using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 3² = 4²
x² + 9 = 16 ( subtract 9 from both sides )
x² = 7 ( take the square root of both sides )
