Jung-Soon has $25 to spend on prizes for a game at the school fair. Lip balm costs $1.25 each, and
mini-notebooks cost $1.50 each. Write a linear equation that can be used to determine how many of
each prize she can buy.
Answer:
1.25x + 1.5y=25
Step-by-step explanation:
let the number of lip balms that can be bought be x and the notebooks be y then their total cost is 1.25x + 1.5y. The total $25 there for the equation becomes 1.25x + 1.5y=25.
The required linear equation can be used to determine how many of each prize she can buy is 1.2x + 1.50y = 25.
Given that,
Jung-Soon has $25 to spend on prizes for a game at the school fair. Lip balm costs $1.25 each, and mini-notebooks cost $1.50 each. Write a linear equation that can be used to determine how many of each prize she can buy is ot be determined.
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Let the number of lip balm that can be purchased be x, and the number of mini notebooks purchased be y,
according to the question,
1.2x + 1.50y = 25
Thus, the required linear equation can be used to determine how many of each prize she can buy is 1.2x + 1.50y = 25.

Write the equation in slope-intercept form of the line given that the slope of the line is 5 and the line passes
through the point (3, 4)
Answer:
let's go...
Step-by-step explanation:
We should use this function to find the standard form the line :
[tex]y - y(given \: point) = (gradient) \times ( \: x - x(g \: p) \: ) \\ y - 4 = 5 \times (x - 3) \\ y - 4 = 5x - 15[/tex]
subtract the sides of the equation plus 4
[tex]y = 5x - 15 + 4 \\ y = 5x - 11[/tex]
And we're done buddy.

Answer:
y = mx + b slope(m) = 1/2 (-2,1)...x = -2 and y = 1 now we sub and solve for b, the y int 1 = 1/2(-2) + b 1 = -1 + b 1 + 1 = b 2 = b so ur equation is : y = 1/2x + 2 <== here is one answer y - y1 = m(x - x1) (slope(m) = 1/2 (-2,1)...x1 = -2 and y1 = 1 now we sub y - 1 = 1/2(x - (-2) = y - 1 = 1/2(x + 2) <== here is another answer

I need HELLLPPPPP. A student bought concert tickets online. The total cost, c, in dollars, of t tickets can be
found using the function below.
c(t) = 87.50t + 12.50
If the student spent a total of $800 on tickets, how many tickets did she buy?
+/-
Answer:
The answer is 9.
Step-by-step explanation: Things to know: c is total cost and t tickets. 800 is the total cost so plug it in to c. You want to get t (tickets) alone.
original: c(t)=87.50t+12.50
Now with the 800: 800=87.50t+12.50
Subtract 12.50 to both sides: 787.5=87.50t
Divide 87.50 to both sides: 9=t
Hopefully this helped. :]

how do I solve this equation 5x+7=3x-5
Answer:
x = -6
Step-by-step explanation:
Simplifying
5x + 7 = 3x + -5
Reorder the terms:
7 + 5x = 3x + -5
Reorder the terms:
7 + 5x = -5 + 3x
Solving
7 + 5x = -5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 5x + -3x = -5 + 3x + -3x
Combine like terms: 5x + -3x = 2x
7 + 2x = -5 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + 2x = -5 + 0
7 + 2x = -5
Add '-7' to each side of the equation.
7 + -7 + 2x = -5 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = -5 + -7
2x = -5 + -7
Combine like terms: -5 + -7 = -12
2x = -12
Divide each side by '2'.
x = -6
Simplifying
x = -6
The solution to the equation 5x + 7 = 3x - 5 is x = -6.
We have,
To solve the equation 5x + 7 = 3x - 5, we need to isolate the variable x on one side of the equation.
Here's how we can do that:
Start by subtracting 3x from both sides of the equation to move all the x terms to one side:
5x + 7 - 3x = 3x - 5 - 3x
Simplifying, we get:
2x + 7 = -5
Next, subtract 7 from both sides of the equation to isolate the term with x:
2x + 7 - 7 = -5 - 7
Simplifying, we get:
2x = -12
Now, to solve for x, we divide both sides of the equation by 2:
(2x)/2 = (-12)/2
Simplifying, we get:
x = -6
Thus,
The solution to the equation 5x + 7 = 3x - 5 is x = -6.

What is the rate of change of the line through (-2,-2) and (-1,5)?
Answer:
The rate of change or the slope is 7. (If you were to graph this, you would use 7/1.
Step-by-step explanation:
To find the slope when you're given two sets of points, you must find the distance from the y values and the distance from the x values!
Y values: distance from -2 to 5 is +7
X values: distance from -2 to -1 is +1
7/1 or just 7.

.Un baúl de 10,5 kg está apoyado en el suelo.Si se tira de él verticalmente hacia arriba con una fuerza de 52,9 N, determina el valor de lanormal.
Respuesta: 50N
Explicación paso a paso:
Dado lo siguiente:.
Tensión (T) = 52,9 N
Masa (m) = 10,5 kg
La normal se obtiene usando la relación:
N = mg - T; donde N = normal, g = aceleración debida a la gravedad (9,8 m / s²)
N = mg - T
N = (10,5 * 9,8) - 52,9
N = 102,9 - 52,9
N = 50 N
