Find the value of x.
19x - 36
6x + 31
Answer:
X= 5
Step-by-step explanation:
The value of x in the equation 19x - 36 and 6x + 31 are 36 / 19 and -31 / 6 respectively.
What is the equation?A formula known as an equation uses the equals sign to denote the equality of two expressions. 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.
Given:
19x - 36 = 0
6x + 31 = 0
Solve the above equation by using the transformed as shown below,
19x - 36 = 0
19x = 36
x = 36 / 19
x = 1.895
For the second one, do the same as shown below,
6x + 31 = 0
6x = -31
x = -31 / 6
x = -5.167

There are 6 ouces of dough and 4 ounces of suase for each person at a party including yourself once you have a total of guest you buy exactly the needed amount of all ingredientsthe dough and sause weigh 130 ounces all together how many ounces of dough did you buy and how many ouces of suase did you buy and how may guests are coming to the party?
Answer:
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces
Step-by-step explanation:
you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain
Dough = 6 ounces
Suase = 4 ounces
Dough + sauce = 6 + 4 = 10
Let x = total number of guests
Dough ingredients + sauce ingredients = 130
10x = 130
Divide both sides by 10
x = 130/10
= 13
x = 13
Number of guests = 13
Total ounces of dough = 6 ounces × 13 guests
= 78 ounces of dough
Total ounces of sauce = 4 ounces × 13 guests
= 52 ounces of sauce
Therefore,
Number of guests = 13
Sauce = 52 ounces
Dough = 78 ounces

e) No sobraron porciones.
f) Véase la imagen adjunta para mayor detalle.
Step-by-step explanation:
Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las razones de consumo de Julián, Mica y Juan, de acuerdo con una lectura cuidadosa del enunciado tenemos que:
[tex]x+y+z=1[/tex] (1)

Determine if it’s a function or not
Answer:
C is not a function but D is
Step-by-step explanation:
For one input, you can only have one output for this to be a function. For table C, the input of 4 has 4 different outputs, so it cannot be a function.
D is a function however, because each input has only one output, even if the output is the same number.

your friend is choosing between two music download companies. MyTunes charges $2.50 per song. Great Songs charges $1.50 per song and has a one-time membership fee of $50. When will Great Songs be the better deal?
Answer:
After 100 songs
Step-by-step explanation:
2.50x=1.50x+50
.50x=50
÷.50
X=100
Great Songs will be the better deal after 100 songs.
What are mathematical operations?Mathematical operations can also be defined by using built-in functions to subtract, divide, and multiply. The arithmetic operator is the one who conducts the arithmetic operation.
* Multiplication procedure: Values on both sides of the operator are multiplied.
For instance, 7×2 = 14
/ Division: Divides the left operand by the right operand
For instance, 4/2 = 2
MyTunes imposes a fee of $2.50 per song. Great Songs charges $1.50 for each song and includes a $50 one-time membership fee, as stated in the question.
Let the songs that come after Great Songs would be x, the better the deal.
⇒ 2.50x = 1.50x + 50
⇒ 0.50x = 50
Divided by 0.50 into both sides of the equation,
⇒ x = 100
Therefore, Great Songs will be the better deal after 100 songs.

Answer:
The correct option is;
(-2, 213) and (2, -213)
Step-by-step explanation:
The reflection of a point across the x-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (x, -y)
The reflection of a point across the y-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (-x, y)
Therefore, from the given points, The reflection across the y-axis of the point (-2, 213) is (2, 213) and the reflection across the x-axis of the point (2, 213) is (2, -213)

Shauna is making accessories for the soccer team. She uses 843.81 inches of fabric on headbands for 29 players and 4 coaches. She also uses 279.56 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
the 25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player
Step-by-step explanation:
The computation of the fabric used on a headband and wristband for each player is as follows:
For headband
= 843.81 inches ÷ (29 players + 4 coaches)
= 843.81 inches ÷ 33
= 25.57 inches
And, for the wristband, it would be
= 279.56 inches ÷ 29 players
= 9.64 inches
Hence, the 25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player

Write an equation of the line in slope-intercept form.
y=
[tex]\huge\boxed{y=-\frac{4}{3}}[/tex]
To find the equation for a line in slope-intercept form, we need to find the slope and the y-intercept.
The y-intercept is easy to find. It's just the value of [tex]x[/tex] when [tex]y=0[/tex]. In this case, the y-intercept is [tex]0[/tex] since the line goes through the origin.
To find the slope, we use the slope formula, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two known points. In this case, we'll use the only two points we have: [tex](0, 0)[/tex] and [tex](-3, 4)[/tex]
[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}\\&=\frac{4-0}{-3-0}\\&=\frac{4}{-3}\\&=-\frac{4}{3}\end{aligned}[/tex]
Finally, we put it all together in slope-intercept form, where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
[tex]y=mx+b\\y=-\dfrac{4}{3}x+0\\\boxed{y=-\frac{4}{3}}[/tex]

The statement were not provided, however, we can deduce the statements from the given equation.
step one:
given
we are told that the cost is expressed as
[tex]c=8p+3[/tex]
