The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $7 and each adult ticket sells for $9.50. There was a total of $883.50 in revenue from all ticket sales and the drama club sold 27 more adult tickets than student tickets. Determine the number of student tickets sold and the number of adult tickets sold.
Answer:
Student tickets 38 and adult tickets 65
Step-by-step explanation:
38x7= $266
65x9.5= $617.50
$266+$617.50=$883.50
Solve for c.
a (b – c) = d
a) c= d - ab/a
b) c= ab – d/b
c) c= ab – d/a
d) c= ab + d/а
Answer:
[tex]c=\frac{ab-d}{a}[/tex]
Therefore, the option 'c' is true
Step-by-step explanation:
Given the expression
[tex]a (b - c) = d[/tex]
Let's solve for c
[tex]a (b - c) = d[/tex]
Step 1: Add -ab to both sides
[tex]ab-ac+\left(-ab\right)=d+\left(-ab\right)[/tex]
[tex]-ac=-ab+d[/tex]
Step 2: Divide both sides by -a
[tex]\frac{-ac}{-a}=\frac{-ab+d}{-a}[/tex]
[tex]c=\frac{ab-d}{a}[/tex]
Hence, we conclude that:
[tex]c=\frac{ab-d}{a}[/tex]
Therefore, the option 'c' is true
Answer:
C) c=ad-d/a

What is the y-intercept of the line that passes through the points (2, -1) and
(-3, 9)?
Answer:
the y intercept is (0, 3)
Step-by-step explanation:
y = mx + c
where m is the slope and c is the y-intercept
[tex]m = \frac{y_2 - y_1}{x_2 - x_1 }[/tex]
[tex]m = \frac{9 - -1}{-3 - 2 }[/tex]
[tex]m = \frac{10}{-5}[/tex]
[tex]m = -2[/tex]
hence, y = -2x + c
input a pair of values, in this case i will use (2, -1)
-1 = -2(2) + c
-1 = -4 + c
-1 + 4 = c
3 = c

Line a is parallel to line b. If the measure of <2 is 78°, what is the measure of <5?
Answer:
The measure of angle 5 is 102°
Solve for x and then find the measure of angle, A.
Answer:
x = 25 ; m∠A = 148°
Step-by-step explanation:
∠A ≅ ∠B (alternate exterior angles)
(6x - 2)° = (4x + 48)°
2x = 50
x = 25
m∠A = 6(25) - 2 = 148°

PLEASE HELP AS SOON AS POSSIBLE (THANK YOU VERY MUCH IF YOU DO)
Answer:In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

Decrease 10kg by 10%
Answer:
if you decrease 10 kg by 10% you get 9 kg
The value after the decrease in 10% is 9 kg
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount be A = 10 kg
Now , the percentage decrease in value = 10 %
So , the equation will be
The amount after decrease =
Total amount - ( percentage decrease in value x total amount )
And , the equation is
The amount after decrease = 10 - ( 10/100 ) x 10
= 10 - 0.1 x 10
= 10 - 1
The amount after decrease = 9 kg
Therefore , the value is 9 kg after decrease in 10 %
Hence , The value after the decrease in 10% is 9 kg

Douglas has a box with 49 paper clips.
Of the paper clips, 15 are yellow, 9 are
red, 6 are blue, 11 are orange and 8
are green. Douglas randomly picks 2
paper clips from the box.
If the first paper clip is red, what is the probability that the second paper clip is blue?
Answer:
6/48 is the likely possibility that he will pull out a blue one.
Step-by-step explanation:
The first thing you will look at is how many blue there is and in this case there is 6. All you have to do (if it didn't already) is add up all of the paperclips and put the blue total number to get your answer. So if there was 49 but he drew out one to make it 48. So the answer is 6/48

HELP ASAP
i need too know these
Answer:
3. y = 4
4. y = 40
Step-by-step explanation:
3. To find y, input the value of 2 for x in the equation y = 3x - 2.
y = 3(2) - 2
y = 6 - 2
y = 4
y is 4 when x is 2.
4. To find the answer we first have to make an equation in y=mx + b form, where b is the y-intercept and m is the slope. We know that the y-intercept is -5 because the table tells us that when x is zero, y is -5. So, we can use the y-intercept and a point In this example I will use point (6, 13)) to find the slope:
Input the values you know into the equation:
13 = 6m - 5
Add 5 to both sides to isolate the 6m:
18 = 6m
Divide both sides by 6 to isolate the m:
3 = m
Our slope is 3. Now that we know the slope and y-intercept, we can make our equation:
y = 3x - 5
We can use this equation to find y when x is 15:
Input 15 in place of x:
y = 3(15) - 5
Solve:
y = 45 -5
y = 40
When x is 15, y is 40.
Hope this helps :)

Charlotte makes crepes using 5/8 cup of milk for every 1/2 cup of flour. She wants to know the amount of milk uses per cup of flour.
Answer:
1 1/4
Step-by-step explanation:
I got it right.
The milk uses per cup of flour will be 5/4 cups of milk per cup of flour.
What is Algebra?Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.
Charlotte makes crepes using 5/8 cups of milk for every 1/2 cup of flour.
She wants to know the amount of milk used per cup of flour. Then we have
⇒ (5/8) ÷ (1/2)
⇒ (5 / 8) x (2 / 1)
⇒ 5 / 4 cups of milk per cup of flour
The milk uses per cup of flour will be 5/4 cups of milk per cup of flour.

Corey, Laura, Paige and Jacob are baking a pumpkin pie. Each of them brings a different ingredient. When the pie is finished, 1/4 of the cinnamon that was brought is left, 1/3 of the nutmeg, 1/2 of the ginger, and 5/8 of the pumpkin remains. Corey's ingredient was used the most. Laura's ingredient was used the least. More of Paige's ingredient was used than Jacob's. Who brought the ginger?
1/4 cinnamon was left, so 3/4 was used.
1/3 nutmeg was left, so 2/3 was used
1/2 of ginger was left so 1/2 was left
5/8 of pumpkin was left so 3/8 was used.
Corey's was used the most, 3/4 is the largest used, so Corey had the cinnamon.
Laura's was used least, 3/8 is the smallest amount so Laura had the pumpkin.
2/3 is more then 1/2, so there was more ginger used than nutmeg.
More of Paige's was used, so Paige had the ginger.

The solution is, the function y=10+×. is plotted below.
What is a function?A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
here, we have,
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
It is a straight line because the degree of the variable or its maximum power is one.
Put x = 0
y = 10 + 0 = 10, therefore one point (0,10)
Put y = 0
0 = 10 +x
Another point since x = -10. (-10,0)
As shown in the graph below, a straight line should be drawn through both locations.
Any point on the line that does not satisfy the equation is a nonexistent point.
Hence the function y=10+×. is plotted below.
