Answer:
Mom=30 Daughter=6
Step-by-step explanation:
M=5×D
M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
x = daughter's age
so:
5x = 6 + 3x
5x - 3x = 6
2x = 6
x = 6/2
x = 3
now just do the equations to find her age
mother before 6 years: 5 x 3
mother after 6 years: 3 x (3+6)
Hopefully, this helps! If it doesn't tell me in the comments so I can explain it better!

What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
The number is,
⇒ 0.407
Now,
Since, The number is,
⇒ 0.407
Hence, The equivalent fraction will be;
⇒ 407/1000 = 0.407

What is the value of x in the triangle?
a 45-45-90 triangle with a leg of length 12 times the square root of 2 and hypotenuse of length x
A.
B.
C.
D.
Answer:
x = 24
Step-by-step explanation:
A 45- 45- 90 triangle is isosceles ( base angles congruent )
The the legs are congruent , both 12[tex]\sqrt{2}[/tex]
Using Pythagoras' identity in the right triangle , then
x² = (12[tex]\sqrt{2}[/tex] )² + (12[tex]\sqrt{2}[/tex] )² = 288 + 288 = 576 ( take square root of both sides )
x = [tex]\sqrt{576}[/tex] = 24
The value of x in the given triangle is 24 units.
What is Pythagoras theorem?The Pythagorean theorem states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
Given that, a 45-45-90 triangle with a leg of length 12 times the square root of 2 and hypotenuse of length x
Let the triangle be ABC, right-angled at B,
Using the Pythagoras theorem, we get,
AB²+BC² = AC²
(12√2)²+(12√2)² = x²
288+288 = x²
x² = 576
x = √576
x = 24
Hence, the length of the hypotenuse is 24 units.

What is the value of y in the triangle?
a 30-60-90 triangle with long leg length y and hypotenuse length 6
A.
B.
C.
D.
Answer: In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse. The shorter leg is the side opposite the 30 degree angle, therefore the shorter leg = 30/2 = 15
By the Pythagorean theorem
the longer leg = √(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units

What is the coefficient of q in the sum of these two expressions?
(23q – 34) and (–16q – r)
Answer:
The coefficient of q is 7
Step-by-step explanation:
The two expressions are
(23q – 34) and (–16q – r)
and .
(–16q – r)
The sum of the two expressions is
23q - 34 + -16q - r
When we group like terms the expression will be,
=23q - 16q - r - 34
When we simplify the expression will now be
=7q - r - 34
The coefficient of q is the constant behind q in the expression.
The coefficient of q is therefore 7.
The table shows how women’s shoe sizes in the United Kingdom compare to women’s shoe sizes in the United States.
a. Write a linear equation to determine the U.S. size y if you are given the U.K. size x.
b. What would be the U.S. shoe size for a woman who wears a U.K. size 7.5
Answer:
A: Y = X + 2.5
B: 10
Step-by-step explanation:
A: To form the equation you have to use one of the numbers in X (U.k Size) for this example we'll use 3 and to form the equation you have to see how much to add to X ( UK size) to get Y ( US size) and in this case it's +2.5
B: You can use the equation we just formed to get this answer by adding 2.5 to 7.5 which will give you 10

The length of the base of the triangle is 6x -2 meters, the height of the triangle is (3x+2)². find the algebraic expression of the area of the triangle (area=bxh/2)
Answer:
27x³ + 27x² - 4 meters²Explanation:
To find the area of the triangle, we must multiply 1/2 x base x altitude to get the answer. But first, we need to simplify the height. We are given the base and the altitude.
Base = 6x - 2Height = (3x + 2)²Solution:
Area of triangle = 1/2 x (6x - 2) x (3x + 2)²=> Area of triangle = 1/2 x (6x - 2) x (3x + 2)(3x + 2)=> Area of triangle = 1/2 x (6x - 2) x (3x + 2)(3x + 2)=> Area of triangle = 1/2 x (6x - 2) x (9x² + 6x + 6x + 4)=> Area of triangle = 1/2 x (6x - 2) x (9x² + 12x + 4)=> Area of triangle = 1/2 x (54x³ - 18x² + 72x² - 24x + 24x - 8)=> Area of triangle = 1/2 x (54x³ + 54x² - 8)=> Area of triangle = (54x³/2 + 54x²/2 - 8/2)=> Area of triangle = 27x³ + 27x² - 4 meters²Hence, the area of the triangle is 27x³ + 27x² - 4 meters².
