A used book store also started selling used CDs and DVDs. In the first week, the store sold 40 used CDs and DVDs, at
$6.00 per CD and $4.00 per DVD. The sales for both CDs and DVDs totaled $180.00. Write a system of equations to
represent this situation
Answer:
6c + 4d = 180
c + d = 40
c represents the CDs and d represents the DVDs.
Need help getting stuck on this problem
Answer:
Variable x in first equationStep-by-step explanation:
Given system
x = 5y - 1x + 2y = 13Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see variable x is isolated in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
Answer:
x
Step-by-step explanation:
x=5y-1--(1)The x variable is isolated here as it's solo on left side
Solve the equations
x+2y=13x=-2y+13--(2)Equate
5y-1=-2y+137y=14y=2x=10-1=9
HELP WILL GIVE YOU Brainiest!!!
Answer:
Step-by-step explanation:
So there we have it, <A=135° and <B=45°. This should check when you add them together ("<A and <B are supplementary which means that together their angles equal 180°"). Does 135°+45=180°? YES!
I Really hope it helps

What is the value of x?
40"
X
55
O A. 85°
O B. 105°
O c. 75°
D. 95°
Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
Answer:
A. 85
Step-by-step explanation:
Youd do 40+55 and that equals 95 and then since a triangle qdds up to 180 degrees, 180-95=85
Solve the one step inequality.
x − 3 ≥ 6
options:
x ≥ 9
x ≤ 9
x ≥ 3
x ≤ 3
Answer:
x≥9
Step-by-step explanation:
I hope this helps you
Answer:
A. x ≥ 9
Step-by-step explanation:
To get the answer you first move all of the terms not containing a variable, to the right side of the inequality. This would cause you to add 3 and 6, giving you 9. To get your answer of x ≥ 9. Hope this helps... have a great day! :))
Please help me solve “Expand log3 4x”
Answer:
Look below.
Step-by-step explanation:
Log3^4x
4xLog3 ------> To expand you would take the exponent and put infront of Log
This is the answer if its expanded. The question was sort of scarce so if this is wrong im sorry.
The expansion of the given logarithm [tex]\mathbf{Log_3 (4x^2)}[/tex] is [tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]
What is the expansion of the logarithm?A Logarithm is an exponent to which a base must be raised in order to result in a given number. The expansion of the logarithm takes a predictable approach and set guidelines.
Using the set formula for solving logarithms;
[tex]\mathbf{log_a(x^n) = n \ log_a \ x}[/tex]
Let's assume that the correct equation given is:
[tex]\mathbf{=Log_3 (4x^2)}[/tex]
Using the above formula, we have
[tex]\mathbf{= 2 Log_3 (4x)}[/tex]
By expansion;
[tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]

what is the leading coefficient ? 6x+2x(3)-5
Answer:
2
Step-by-step explanation:
The correct order in which the equation is written would be:
[tex]2x^{3} + 6x - 5[/tex]
So, when ordered correctly the leading coefficient is the first number, so with this equation that would be 2.

Find the y intercept and the slope
Answer:
The slope is -1/2 and the y intercept is 1
Step-by-step explanation:
Please explain how to solve this and the answer
Looking at the letter arrangement in the problem B is similar to W
Set those equal to each other and solve.
X + 24 = 2x -2
Subtract x from both sides:
24 = x -2
Add 2 to both sides:
X = 26
Now replace x in the equation for B
2x -2 = 2(26)-2 = 52-2 = 50
B = 50 degrees
The 3rd choice is the answer.

Solve the equation 18+a= -50
Answer:
-68
Step-by-step explanation:
Subtract 18 from each side of the equation.
a + 18 = -50
-18 -18
Turn -50 - 18 into -50 + (-18) because you need to add the opposite.
a = -50 + (-18)
a = 68

13, 14, 17
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
A. Acute TriangleStep-by-step explanation:
Lets verify with Pythagorean:
17² = 28913² + 14² = 169 + 196 = 365289 < 365The angle opposite to a greater side is less than 90° and the sum of the squares are close.
It means all three angles are less than 90°.
With this the triangle is acute.
Correct choice is A.
