She subtracted 5x instead of distributing. This is incorrect, because since it is in ( ), it has to be multiplied by 3.
Correct: 3(5x + 9) = 15x + 27
12x + 3 = 15x + 27
Noah:
Added 15x instead of subtracting. This is incorrect, because to combine like terms on each side you would add a negative number and subtract a positive number.
Correct: 12x + 3 = 15x + 27
12x - 15x = 27 - 3
-3x = 24
x = 24 / -3

100% is an integer multiple of 10%
Step-by-step explanation:
100% is not an integer multiple of 30%, so it is difficult to use 30% directly to determine the value of 100%. Dividing 30% by 3 to get 10% then gives you a value that can be multiplied by 10 to find 100%.
Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?
Answers
Answer:
16,700
Step-by-step explanation:
Given that,
Earning of Ethan = 38,428
Ethan spends 21,728 on expenses.
We need to find the amount of money he has left over. It can be calculated as follows :
Left money = Earning - Spent
= 38,428 - 21,728
= 16,700
So, he has left over 16,700.
2(d − 6) − 3 = 1 solve for d
Answers
Answer:
d = 8
Step-by-step explanation:
2(d -6) - 3 = 1
+3 +3
2(d-6) = 4
/2 /2
(d-6) = 2
+6 +6
(d) = 8
d = 8
Answer:
d=8
Step-by-step explanation:
2(d-6)-3=1
Add 3 to both sides:
2(d-3)+3=1+3
Simplify:
2(d-6)=4
Divide both sides by 2:
2(d-6)/2=4/2
Simplify:
d-6=2
Add 6 to both sides:
d-6+6=2+6
Simplify:
d=8

how to write this in slope intercept form
Answers
Explanation: slope intercept form is (y = mx + b) since you have to plug-in the 10/hour, the equation would need to be $10 depending on how much hours. But, we don’t know how much hours so that would be so we put that as x (10x). Then , just plug-in the rest of the variables and that would bring you with y = 10x + b. Hope this is right :)

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°
Answers
Answer:
m∠A = 50°
m∠B = 70°
m∠C = 60°
Step-by-step explanation:
Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°
In a Triangle, the sum of the interior angles of a triangle = 180°
Step 1
We solve for x
Hence:
m∠A + m∠B + m∠C= 180°
(x-10)°+ (2x-50)°+ x° = 180°
x - 10 + 2x - 50 + x = 180°
4x - 60 = 180°
4x = 180° + 60°
4x = 240°
x = 240°/4
x = 60°
Step 2
Solving for each measure
x = 60°
m∠A=(x-10)°
= 60° - 10°
= 50°
m∠B=(2x-50)°
= 2(60)° - 50°
= 120° - 50°
= 70°
m∠C=x°
= 60°

Tickets to a family concert cost $10 for adults and $3 for children. The concert
organizers collected a total of $900 from ticket sales.
Given the function 10A + 3C = 900:
A) Write an equation to represent C as a function of A. (In essence, solve the equation
for C).
B) Write an equation to represent A as a function of C. (In essence, solve the equation
for A)
**Use math type to type your answer**
Answers
Answer:
3C=900-10A
Step-by-step explanation:
The given equation can be written to represent C as a function of A and A as a function of C as C = 300 - 10/3A and A = 90 - 3/10C respectively.
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
(a) The function for the cost of tickets is given as 10A + 3C = 900.
It can be written to represent C in terms of A as,
10A + 3C = 900
⇒ 3C = 900 - 10A
⇒ C = 300 - 10/3A
(b) It can be written to represent A in terms of C as,
10A + 3C = 900
⇒ 10A = 900 - 3C
⇒ A = 90 - 3/10C
Hence, the given equation can be rewritten as C = 300 - 10/3A and A = 90 - 3/10C respectively.

======================================
Work Shown:
c = price of coat before discount
0.33c = discount = amount you save
c - 0.33c = original price minus discount = final price
c - 0.33c = 1c - 0.33c = (1-0.33)c = 0.67c = final price
In short, c - 0.33c = 0.67c
They are two ways of expressing the same thing.
You can think of it like saying 100% - 33% = 67%
If you save 33%, then you still have to pay the remaining 67% of the original cost.
-------------
Example:
Let's say the coat is $100 before the discount
c = 100
0.33*c = 0.33*100 = 33 dollars is how much you save
c - 0.33c = 100 - 33 = 67 dollars is the final price
0.67c = 0.67*100 = 67 matches with the previous figure above

The sum of the interior angle measures of a convex octagon is 1080. the correct option is A.
What is an octagon?An octagon is an 8-gon, or polygon with eight sides, in geometry. The Schläfli symbol for a regular octagon is 8, and it can also be built as a nearly regular truncated square.
The interior angle will be calculated as,
Angle = (n - 2) x 180
Angle = ( 8 - 2 ) x 180
Angle = 1080
Therefore, the sum of the interior angle measures of a convex octagon is 1080. the correct option is A.
