3x + 2(4 + 6x) = 113
Explain what you did in each step of your solution.
Answers
Answer:
x = 7
Step-by-step explanation:
So first, multiply everything inside the ( ) by 2
So then, the equation will look like this: 3x + 8 + 12x = 113
Then, combine like terms, which leave the equation to look like this:
15x + 8 = 113
Then subtract 8 from both sides, leaving the equation like this : 15x = 105
Last step, divide both sides by 15, which leave you with x = 7

cause it’s y=mx+b so you do the slope with going up/down as numerator and left or right as denominator. if the line is goin down from left to right it’s slope will be negative, if it’s going up from left to right it’s positive. then the b is just the y-intercept
Solve this equation

Answers
Answer:
Total cost= $12,300
Step-by-step explanation:
Giving the following information:
Fixed cost= $1,500
Monthly cost= $450
To calculate the total cost, we need to use the following formula:
Total cost= fixed cost + unitary variable cost*x
x= number of units
For 2 years:
Total cost= 1,500 + 450*24
Total cost= $12,300

What is a unitary method?
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Deron recorded his heart rate as 204 beats in 3 minutes.
∴ How many times his heart beats in one minute or the unit rate in beats per minute can be obtained if we divide the total no. of beats by total no. of minutes which is,
= (204/3) beats per minute.
= 68 beats per minute.

Please check the explanation below.
Step-by-step explanation:
We know that a binary relation between two sets is termed as a function which associates every element of the first set to exactly one element of the second set.In other words, in order for relation to be a function, we must make sure there must be no repetition of 'x' coordinate values, as it would violate the fundamental definition of a function.
A) (2, 5), (5, 7), (7, 9)
Here, the x-coordinates are: 2, 5, and 7
At x = 2, y = 5
At x = 5, y = 7
At x = 7, y = 9
As there is no repetition of x-coordinates.Thus, the coordinate pairs (2, 5), (5, 7), (7, 9) represent the function.
B) (2, 3), (1, 4), (2, 8),(0, 1)
Here, the x-coordinates are: 2, 1, 2 and 0
At x = 2, y = 3
At x = 1, y = 4
At x = 2, y = 8
At x = 0, y = 1
Please observe that the x-coordinate values i.e. x=2 are repeated.
Thus, the coordinate pairs (2, 3), (1, 4), (2, 8),(0, 1) does not represent the function.
C) (4, 8), (5, 8), (6, 8)
Here, the x-coordinates are: 4,5 and 6
At x = 4, y = 8
At x = 5, y = 8
At x = 6, y = 8
As there is no repetition of x-coordinates.Thus, the coordinate pairs (4, 8), (5, 8), (6, 8) represent the function.
Please note that it does not matter if y-values are repeated. Just remember, we can not have repeated x-values.D) (-1, 4), (0, -1), (8, 3)
Here, the x-coordinates are: -1, 0, and 8
At x = -1, y = 4
At x = 0, y = -1
At x = 8, y = 3
As there is no repetition of x-coordinates.Thus, the coordinate pairs (-1, 4), (0, -1), (8, 3) represent the function.
E) (1, 8), (8, 1), (1, 3)
Here, the x-coordinates are: 1, 8, and 1
At x = 1, y = 8
At x = 8, y = 1
At x = 1, y = 3
Please observe that the x-coordinate values i.e. x=1 are repeated.
Thus, the coordinate pairs (1, 8), (8, 1), (1, 3) does not represent the function.
F) (9, 0), (9, 1), (9, 2), (9, 3)
Here, the x-coordinates are: 9, 9,9 and 9
At x = 9, y = 0
At x = 9, y = 1
At x = 9, y = 2
At x = 9, y = 3
Please observe that the x-coordinate values i.e. x=9are repeated.
Thus, the coordinate pairs (9, 0), (9, 1), (9, 2), (9, 3) does not represent the function.
En una tienda se anuncia la rebaja de 20% en todos sus artículos. Rafael elije una camisa y al llegar a la caja le informan que esa camisa, por traer etiqueta roja, cuenta con un descuento adicional del 15%. Si Rafael pago $510.00, ¿cual era él precio de la camisa sin los descuentos?
Answers
9514 1404 393
Answer:
$750
Step-by-step explanation:
The 20% discount multiplies the price by (1 - 20%) = 0.80.
The 15% discount multiplies the price by (1 - 15%) = 0.85.
After applying the discounts to the initial price P, we have ...
P(0.80)(0.85) = $510
P = $510/(0.80·0.85) = $750
The price before discounts was $750.
