Answer: Dad = 3 hours
Mom = 11 hours
Step-by-step explanation:
Let the number of hours driven by her mum be m.
Let the number of hours driven by her dad be d.
We can form equation from the question as:
d + m = 14 ........... i
60d + 65m = 895.......... ii
Since d + m = 14, d = 14 - m
Substitute 14 - m into d in equation ii
60d + 65m = 895
60(14 - m) + 65m = 895
840 - 60m + 65m = 895
840 + 5m = 895
5m = 895 - 840
5m = 55
m = 11
The mother drove for 11 hours
Since d + m = 14
d + 11 = 14
d = 14 - 11
d = 3
The father drive for 3 hours
A realtor is paid $24 per hour and $20 for each sale she makes. She wants to earn $2,000 in a 10-hour work period. Write an equation that represents the number of sales, x, the saleswoman must make in a 10-hour period to earn $2,000. How many sales must she earn to reach her goal?
Answer:
2000 = 24x + 20y (x represents hours and y represents money per sale)
she must make 88 sales
Step-by-step explanation:
2000 = 24(10) + 20y
2000 = 240 + 20y
-240 = -240
1760 = 20y
/20 = /20
88 = y

x=2y-4
7x+5y=-66
what is the x- value
Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
Line n is defined by the equation y = 3x - 5. If line n undergoes a dilation with a scale factor of 3 and center P, which equation will define the image of the line?
A. y = 3x + 13
B. y = 3x - 23
C. y = 9x - 5
D. y = 9x - 15
The required equation for the dilated image of the line is y = 9x - 15. Option D is correct.
What is the scale factor?The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
Line n is defined by the equation y = 3x - 5.
Line n undergoes a dilation with a scale factor of 3 and center P,
Since the dilation of line n with factor 3, increase the slope of a line by 3 times and change the intercept simultaneously.
y = 3(3x - 5)
y = 9x - 15
Thus, the required equation of dilated image of the line is y = 9x - 15.

Answer:
Al evento entraron 82 adultos y 18 menores de edad.
Step-by-step explanation:
De acuerdo a la información proporcionada, puedes plantear las siguientes ecuaciones:
x+y=100 (1)
90x+45y=8190 (2), donde:
x es el número de adultos
y es el número de menores de edad
Puedes despejar x en (1):
x=100-y (3)
Después, puedes reemplazar (3) en (2):
90(100-y)+45y=8190
9000-90y+45y=8190
9000-8190=90y-45y
810=45y
y=810/45
y=18
Ahora, puedes reemplazar el valor de y en (3) para encontrar x:
x=100-y
x=100-18
x=82
De acuerdo a esto, la respuesta es que al evento entraron 82 adultos y 18 menores de edad.

What is meant by functions?A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain. In mathematics, a function is a mathematical expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.A function is a relationship between a set of inputs and one output. Every function has its own domain, codomain, and range.When working on a project, it is common for some tasks to need to be repeated with different input. To ensure that the analyses are performed consistently, it is critical to wrap the code in a named function that is called each time it is required.Therefore,
