Answer: A
Step-by-step explanation:
I had this question on my test yesterday lol
The system of equation will be ". a + c = 90 8a + 5c = 525"
Let the number of adults tickets be represented by a
Let the number of children tickets be represented by c.
Since 90 total tickets were sold, this can be represented by the equation:
a + c = 90
Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:
8a + 5c = 525
Therefore, the correct option is A.

Whats the answer plz help
Answer:
In this case, you can simply treat the > sign like an = sign. The only time you would need to worry about is when multiplying or dividing by negative numbers.
2x + 3 > 13
2x + 3 - 3 > 13 - 3
2x > 10
2x / 2 > 10 / 2

Answer:
1.1 Solve x-3y+7 = 0
recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y+7 = 0 and calculate its properties

Answer: Solution: (-4, 1)
Step-by-step explanation:
x = 3y - 7
4x + 5y = -11
Substitute x for 3y - 7
4x + 5y = -11
4 (3y - 7) + 5y = -11
12y - 28 + 5y = -11
17y - 28 = -11
Add 28 to both sides
17y = 17
y = 1
x = 3y - 7
x = 3(1) - 7
x = 3 - 7
x = -4
Solution: (-4, 1)

What is the equation of the line with a slope of 2 through (-4, 6) in point-slope form?
O y = 2x + 14
Oy-6 = 2 (x +4)
Oy= 2x – 14
Oy+6 = 2 (x – 4)
Answer:
y - 6 = 2(x + 4)
Step-by-step explanation:
Point slope form is y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex]).
[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that they give you in the problem, which is (-4, 6), and m is the slope, which is 2.
When you plug everything in, you should get
y - 6 = 2(x + 4).

Step-by-step explanation:
Sarah hired a painter to paint her bedroom walls and ceiling. Each of the four bedroom walls is 18 ft. Long and 8 ft. High. Two walls each have one door, and both doors measure 3 ft. By 7 ft. One wall has a window that is 3 ft. By 5 ft. The doors and window do not have to be painted. A gallon of paint can cover 300 ft.2. A hired painter claims that he will need three gallons to paint the one room. Is the estimate correct?
Answer:
The estimate is not correct?
Step-by-step explanation:
Given data
Area of wall = 18*8
=144ft^2
=4*144
=576ft^2
Area of doors
=3*7
=21ft^2
=2*21
=42ft^2
Area of window
=3*5
=15ft^2
Hence the total surface area of the room
=576-42-15
=519ft^2
The amount of paint needed= 519/300= 1.73
Approximately 2 gallons
We are told that 1 gallon will cover 300ft^2
Hence 3 gallons will cover 300*3= 900ft^2
Therefore the painter overestimated the amount of paint needed
As 2 gallons will do the job

Answer:
(4, 2 ) and (5, - 4 )
Step-by-step explanation:

6x + 2y = 28 → (1)
x = 2y → (2)
Substitute x = 2y into (1)
6(2y) + 2y = 28
12y + 2y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Substitute y = 2 into (2) for corresponding value of x
x = 2(2) = 4
solution is (4, 2 )
(4)
x + y = 1 → (1)
2x + y = 6 → (2)
Rearrange (2) expressing y in terms of x by subtracting 2x from both sides
y = 6 - 2x → (3)
Substitute y = 6 - 2x into (1)
x + 6 - 2x = 1
- x + 6 = 1 ( subtract 6 from both sides )
- x = - 5 ( multiply both sides by - 1 )
x = 5
Substitute x = 5 into (3) for corresponding value of y
y = 6 - 2(5) = 6 - 10 = - 4
solution is (5, - 4 )

Lydia invested $83,000 in an account paying an interest rate of 6.7% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $210,100?
Answer:
14
Step-by-step explanation:
The required time for Lydia's account to reach $210,100 is 13.9 years.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
First, convert R as a percent to r as a decimal
r = R/100
r = 6.7/100
r = 0.067 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.067/12)] )
t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.0055)] )
t = 13.9 years
Thus, the required time for Lydia's account to reach $210,100 is 13.9 years.

Solve these simultaneous equations:
3. 5x – 3y = 15 4x 3y = 6
2x + 5y = 26 4x + 3y = 24
3x + 3y = 39 2x - 3y = - 2
Answer:
1) We have the system:
5*x - 3*y = 15
4*x + 3*y = 6
To solve this, we first need to isolate one of the variables in one of the equations, let's isolate x in the first equation:
x = 15/5 + (3/5)*y = 3 + (3/5)*y
Now we can replace this in the other equation to get:
4*( 3 + (3/5)*y) + 3*y = 6
and solve this for y.
12 + (12/5)*y + 3*y = 6
(12/5 + 3)*y = 6 - 12 = -6
(12/5 + 15/5)*y = -6
(27/5)*y = -6
y = -6*(5/27) = 1.11
Now we can replace this in the equation:
x = 3 + (3/5)*y
To get the value of x.
x = 3 + (3/5)*1.11 = 3.67
Then the solution of this system is the point (3.67, 1.11)
2) Now we have the system:
2*x + 5*y = 26
4*x + 3*y = 24
The solution method is the same as before:
x = 26/2 - (5/2)*y = 13 - (5/2)*y
Now we replace this in the other equation:
4*( 13 - (5/2)*y) + 3*y = 24
52 - 10*y + 3*y = 24
52 - 7*y = 24
52 - 24 = 7*y
28 = 7*y
28/7 = y
4 = y
now we replace this in the equatio:
x = 13 - (5/2)*y
x = 13 - (5/2)*4 = 13 - 10 = 3
The solution of this sytem is (3, 4)
3) Now we have the system:
3*x + 3*y = 39
2*x - 3*y = -2
first we isolate x in the first equation:
x = 39/3 - 3*y/3 = 13 - y
Now we can replace this in the other equation:
2*(13 - y) - 3*y = -2
26 - 2*y - 3*y = -2
26 - 5*y = -2
26 + 2 = 5*y
28 = 5*y
28/5 = y = 5.6
Now we can replace this in the equation:
x = 13 - y
To get the x-value
x = 13 - 5.6 = 7.4
Then the solution for this system is (7.4, 5.6)
