Una mamá tiene el cuádruplo de la edad de su hijo, y dentro de 5 años, tendrá el triple de años que el. Indica que edad tienen ambos.
Answer:
The son age is 10 years
And, his mother age be 40 years
Step-by-step explanation:
Given that
The mother is four times the age of her son
And, in 5 years, she will be three times as old as him
We need to find out the ages of both
Here we assume that the age of her son be x
So the mother age be 4x
Now in 5 years, her mother would be 3 times as old as his son
So,
4x + 5 = 3(x + 5)
4x + 5 = 3x + 15
x = 10
The son age is 10 years
And, his mother age be 40 years
What is the value of x?
Answer:
5 units (you are right!)
Step-by-step explanation:
The triangles ABD and BCD are similar.
Therefore,
[tex]\frac{x}{10}=\frac{10}{4x} \\4x^{2}=100\\x^{2}=25\\x=5[/tex]

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Clayton gets paid at home for doing extra chores. Last week, he did 4 loads of laundry and 5 loads of dishes, and his parents paid him $14. The week before, he finished 4 loads of laundry and 10 loads of dishes, earning a total of $24. How much does Clayton earn for completing each type of chore? Clayton earns $ per load of laundry and $ per load of dishes.
Answer:
$1.00 per load of laundry, $2.00 per load of dishes
Step-by-step explanation:
4($1.00) = $4
5($2.00) = $10
This equals $14, when he does 10 loads of dishes the number changes to $20 and by adding $20 to $4, that equals $24.
The answer is $1.00 per a load of laundry, $2.00 per load of dishes
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Last week, he did 4 loads of laundry and 5 loads of dishes, and his parents paid him $14. The week before, he finished 4 loads of laundry and 10 loads of dishes, earning a total of $24.
Clayton's earnings will be calculated as,
4($1.00) = $4
5($2.00) = $10
This equals $14, when he does 10 loads of dishes the number changes to $20, and by adding $20 to $4, that equals $24.

help please! quadratic equation and stretch factor
Answer:
Equation: f(x)=x²-4x+3
Stretch factor: a=1
Step-by-step explanation:
Notice the x-intercepts are (1,0) and (3,0) which can help us determine the equation by setting their expressions equal to 0 and expanding:
(x-1)(x-3)=0
x²-4x+3=0
Therefore, the equation is f(x)=x²-4x+3 where the stretch factor is a=1

The other legs of the right-angle triangle will be 12.23 units and 11.81 units.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The right angle triangle is shown with the angle of 44° and the length of the hypotenuse is 17 units.
Then the measure of the length of x will be given by a cosine angle of 44°.
cos 44° = x / 17
x = 12.23 units
Then the measure of the length of y will be given by a sine angle of 44°.
sin 44° = y / 17
y = 11.81 units
Thus, the other legs of the right-angle triangle will be 12.23 units and 11.81 units.
