What is the solution to the gaming systems of linear equations 2X plus 3Y equals 13 for a 6+ 6Y equals 14
Answer:
(9/2, 4/3) or just x = 9/2, y = 4/3. (it's the same thing)
Step-by-step explanation:
First, multiply the first equation 2x + 3y = 13 by 2, so that you get 4x + 6y = 26. Now you have the same coefficient for y. Now, subtract the second equation 6y = 8 (i simplified it first) from the first one that is doubled. After that, you would have just one equation, 4x = 18. So x = 18/4 = 9/2. Substitute x to solve for y, and you'd get 4/3.

Answer:
(x, y) = (-6, 8 1/3)
Step-by-step explanation:
The system of equations appears to be ...
2x +3y = 136x +6y = 14Dividing the first equation by 2 gives ...
3x +3y = 7
Subtracting the first equation from this, we get ...
(3x +3y) -(2x +3y) = (7) -(13)
x = -6
Then substituting for x in the first equation, we have ...
2(-6) +3y = 13
3y = 25 . . . . . . . . add 12
y = 25/3 = 8 1/3 . . . . divide by 3
The solution is (x, y) = (-6, 8 1/3).
Each day a company used 2 / 8 of a box of paper. How many would they have used after 5 days?
Answer:
Now to secrtly stalk this man
Step-by-step explanation:
They have used after 5 days, 1 full box and 1/4 of another box.
What is fraction?Fractions are used to represent smaller pieces of a whole.
Given that, Each day, a company used 2 / 8 of a box of paper.
They are using 1/4 box of paper each day,
So, after 5 days = 5*1/4 = 5/4 = 1+ 1/4
Hence, They have used after 5 days, 1 full box and 1/4 of another box.

g(x) = (x + 8)27
A. left 8 units
B. right 8 units
C. up 8 units
D. down 8 units
The correct translation will be;
⇒ left 8 units
What is Translation?A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
The function is,
⇒ f (x) = x²
And, The graph after translation is,
⇒ g (x) = (x + 8)²
Now,
Since, The graph after translation is,
⇒ g (x) = (x + 8)²
And, The function is,
⇒ f (x) = x²
So, We can say that the translation used is,
⇒ left 8 units.
Thus, The correct translation is;
⇒ left 8 units

an equation that is perpendicular to x-3y=3 and pases through the point (5,-9) in slope-intercept form
Answer:
y = - 3x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 3y = 3 ( subtract x from both sides )
- 3y = - x + 3 ( divide all terms by - 3 )
y = [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (5, - 9) into the partial equation
- 9 = - 15 + c ⇒ c = - 9 + 15 = 6
y = - 3x + 6 ← equation of perpendicular line

4. Calculate the expected value for the spinner at right?
(3pts)
8
1200
24
6
Answer: The expected value is 12.44
Step-by-step explanation:
The expected value can be calculated as:
EV = ∑xₙ*pₙ
Where xₙ is the n-th outcome. For the case of the spinner we have 3 possible outcomes:
x₁ = 8
x₂ = 6
x₃ = 24
And pₙ is the probability of the n-th event.
For the case of the spinner, the probability of each section will be equal to the quotient between the degrees of each arc, and the total number of degrees in a circle (360°).
First, we can see that for outcome = 8, the angle is a right angle, then it is equal to 90°, then the probability of this event will be:
p₁ = 90°/360° = 0.25
For outcome = 24, we have an angle of 120°, then the probability for this event is:
p₃ = (120°/360°) = 0.33
And the angle for the third arc must be such that:
90° + 120° + A = 360°
then:
A = 360° - 90° - 120° = 150°
Then the probability for the outcome = 6 is:
p₂ = (150°/360°) = 0.42
Now we can find the expected value as:
EV = (8*0.25 + 6*0.42 + 24*0.33) = 12.44

Answer:
A. There is a 1/4 chance.
Step-by-step explanation:
There are 8 outcomes if a coin is flipped 3 times.
Of these, 4 start with tails.
Since 4 is the denominator here, C (3/8) is out.
Also 4 doesn't have 3 as a factor, so B (1/3) is also out.
After the tails flip, two heads follow.
That's one of four of the combinations starting with tails (THH, THT, TTH, TTT, so D is out, leaving A as our answer! (We would need two for A to work)
A production company spent 45
1
2 days filming its first movie. The company's second movie was filmed in 7
3
4 weeks. Find the ratio of the first movie's filming time to the second movie's filming time. Compare in weeks.
Answer:
26 /33
Step-by-step explanation:
Given that :
Number of days taken filming first movie = 45 1/2
Number of weeks spent filming second movie = 8 1/4
Concerning days to weeks ;
45 1/2 days = 91/2 days = 91/2 ÷ 7 ;
91 / 2* 1/7 = 91/14 = 6. 5 weeks
Hence,
Ratio of first week fuming to second week filming ;
6.5 weeks : 8 1/4 weeks
6 1/2 : 8 1/4
13 / 2 : 33 /4
13 / 2 * 4 /33
52 / 66
26 / 33

~[tex]\frak{LoveYourselfFirst:)}[/tex]
Hey there!
Do you remember what the Distributive property states? If not, no worries! Here's what this property states:
a(b+c)=ab+ac
In this formula, a, b, and c can be
Constants. These are numbers like 1, 2, 3, or -1, -2, -3... or even fractions, decimals... (all real numbers)Variables. These are letters like d, a, s, e, t, k, a...Variables can have a number next to them; it's called a coefficient.Now that we know what this property states, let's simplify this expression.
5(x-2)
First, multiply 5 times x:
5x (5 is the coefficient of x, by the way)
Then, multiply 5 times -2 (please pay attention to the sign) :)
-10
Put both terms together.
Hence, the simplified expression is
[tex]\boxed{\boxed{\bold{5x-10}}}[/tex]
Is it possible to simplify the expression any further? No.
Why? Because 5x and -10 aren't like terms, so we cannot combine them.
Hope everything is clear.

question:find the angle measure of the missing angle
if you can pls explain
Answer:
85°
Step-by-step explanation:
So in geometry, the formula to find the sum of all interior angles is denoted as follows:
n = number of sides in the polygon
( n - 2 ) × 180° = sum of the interior angles
Using that formula, a triangle has 3 sides, so
n = 3 , therefore:
= ( 3 - 2 ) × 180°
= 1 × 180°
= 180°
Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:
34° + 61° + x = 180°
Solve for x.

Answer:
- 3 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Any number combined with it's opposite will make zero. The opposite of a number is the same number with it's sign flipped. For example, the opposite of 5 is -5, and the opposite of -3 is 3. If I combine any number, for example 10, with it's opposite, in this case -10, it will make zero. (10 - 10 = 0.) Hope this helps!
