the sum of three numbers is 66.the second number is twice the first number and the third number is 3x the first number

what is the first and second number?​

Answers

Answer 1

Answer:

The first number: 11;

The second number: 22;

The third number: 33

Step-by-step explanation:

The first number: 11

The second number: 11 x 2 = 22

The third number: 11 x 3 = 33

11 + 22 + 33 = 66

Answer 2

Answer:

11 and 22

Step-by-step explanation:

let the first number ne x then second is 2x and third is 3x and sum is

x + 2x + 3x = 66 , that is

6x = 66 ( divide both sides by 6 )

x = 11

2x = 2 × 11 = 22

first number is 11 and second number is 22

Answers

Answer and Step-by-step explanation:

First, distribute the numbers outside of the parenthesis to the numbers on the inside.

-12x - 9 + 24x + 4 = 43

Combine like terms.

12x - 5 = 43

Add 5 to both sides.

12x = 48

Divide by 12 on both sides of the equation.

x = 3 <- This is the answer.

A number is multiplied by 9 , and that product is added 3. The sum is equal to the product of 3 and 7 . Find the number.

Answers

Answer:

The unknown number is 2.

Step-by-step explanation:

Let x represent the unknown number.

It is multiplied by 9 then added to 3. Hence, it can be represented by the expression:

[tex]9x + 3[/tex]

The sum is equal to the product of 3 and 7, or 21. Therefore:

[tex]9x + 3 = 21[/tex]

Solve for x. Subtract 3 from both sides:

[tex]9x = 18[/tex]

And divide both sides by 2. Hence:

[tex]x = 2[/tex]

In conclusion, the unknown number is 2.

ANSWER:
the number is 2

If a function is defined by the equation y = 1/2x -3/2 , which equation defines the inverse of this function?

Answers

Answer:

B

Step-by-step explanation:

Rearrange the equation making x the subject

y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{2}[/tex] ( multiply through by 2 to clear the fractions )

2y = x - 3 ( add 3 to both sides )

2y + 3 = x

Change y back into terms of x with x being the inverse function, that is

y = 2x + 3 → B

solve for y
-10x + 2y =4

Answers

Answer:

y = 5x + 2

Add 10x to both sides

2y = 10x + 4

Divide both sides by 2

y = 5x + 2

The length of the parallel sides of a trapezium are 3cm and 1 cm, and the distance between them is 1 cm. What is its area?​

The height of a triangle is 5 cm more than its base. The area of the triangle is 52 square centimeters. What is the base of the triangle?

Answers

Answer:

the base is 8 cm

Step-by-step explanation:

basically, we need to set up a system of equations.

if we know the area of a triangle is 1/2bh, and that h = b + 5, (because we want them to equal one another in the equation), we can then make two different equations and substitute the h for b.

1/2bh = 52 and h = b+5

subsitute in the (b+5) for the h in the first equation to get

(1/2)(b)(b+5) = 52

multiply both sides by two to get rid of the 1/2

b)(b+5) = 104

now multiply the bs together!

b^2 + 5b = 104

If you know how to factor, we can make this

b^2 +5b -104 and then

(b+13)(b-8) = 0

solve for b to get b = -13, 8, and -13 isn't a real distance, so the only option for b is 8 square centimeters.

Plugging this back into the original equations to get the height (and checking that it is actually right,) we get a height of 13.

When you plug in the 13 and 8 into the area equation, you get

(8)(13)(1/2) = 52

52 = 52

so it works!

lmk if anything is confusing- i know I kind of breezed by the factoring part, but if you have a calculator you can keep dividing 104 by random numbers until you get the right difference if you get kind of lost. The formula

[-b+-sqrt(b^2-4ac)]/2a is another way you could always get the right answer, (from the form Ax^2 + Bx + C), but it's pretty time consuming and I'm not sure whether you've actually learned that yet..

hope that helps! :)

Plss help number is 21952 and 115248

Answers

Answer:

Step-by-step explanation:

Bonjour,

2^4 * 7^3 => 16* 343 = 5488

21 952 / 5 488 =4

115 248/5 488 =  21

9514 1404 393

Answer:

  2⁴·7³

Step-by-step explanation:

The set of primes that are factors of 21952 is {2, 7}.

The set of primes that are factors of 115248 is {2, 3, 7}.

Common factors are primes that are in the intersection of these sets: {2, 7}. The index associated with the greatest common factor is the smallest index of each of these primes in the prime factorization of those numbers.

The prime 2 is seen to have indices of 6 and 4. 4 is the smallest.

The prime 7 is seen to have indices of 3 and 4. 3 is the smallest.

So, the Highest Common Factor of the two numbers is 2⁴·7³.

The midpoint of AB is (1, 2). The coordinates of A are (-3,6).Find the coordinates of B.

Answers

Midpoint has coordinates [tex](x_m,y_m)[/tex] which equal to,

[tex]x_m=\frac{x_1+x_2}{2}[/tex]

[tex]y_m=\frac{y_1+y_2}{2}[/tex]

We know the coordinates of a midpoint as well as the coordinates of [tex]A(x_1,y_1)[/tex] so we should be able to find coordinates of [tex]B(x_2,y_2)[/tex].

First solve both equations for [tex]x_2[/tex] and [tex]y_2[/tex] respectively,

[tex]x_2=2x_m-x_1[/tex]

[tex]y_2=2y_m-y_1[/tex]

Now insert the data,

[tex]x_2=2\cdot1-(-3)=\boxed{5}[/tex]

[tex]y_2=2\cdot2-6=\boxed{-2}[/tex]

The coordinates of B are therefore [tex](5,-2)[/tex].

Hope this helps :)

The midpoint of AB is (1, 2) the coordinates of A are (-3,6) coordinates of B coordinates of point B are (5, -2).

To find the coordinates of point B given that the midpoint of AB is (1, 2) and the coordinates of A are (-3, 6),  use the midpoint formula:

Midpoint formula: M(x, y) = ((x1 + x2) / 2, (y1 + y2) / 2)

Given that M is the midpoint (1, 2) and A is (-3, 6), we have:

(1, 2) = ((-3 + x2) / 2, (6 + y2) / 2)

Solve for x2 and y2:

For x-coordinate:

1 = (-3 + x2) / 2

2 = -3 + x2

x2 = 2 + 3

x2 = 5

For y-coordinate:

2 = (6 + y2) / 2

4 = 6 + y2

y2 = 4 - 6

y2 = -2
