Camila, and Camila is twice as old as Luna, what are the ages of the
three sisters?

Create an equation with only one variable.

Answers

Answer 1

9514 1404 393

Answer:

Luna is 9Camila is 18Ava is 24

Step-by-step explanation:

We can express all of the ages in terms of Luna's age. Letting L represent Luna's age, we have ...

Luna's age: LCamila's age: 2LAva's age: 2L +6

The total of their ages is then ...

  L +2L +(2L+6) = 51 . . . . an equation with one variable

  5L = 45

  L = 9

Luna is 9, Camila is 18, and Ava is 24.

I have $460 less than dotun. Altogether we have $1280. How much do we have

Answers

Answer:

you have $180, total there is $1280

Step-by-step explanation:

The required amount we have is given as $410, as of the given condition.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Let the amount we and Dotun has to be x and y,
According to the question,
x  = y - 460- - -- - -(1)

x + y = 1280 - - - (2)
From equation 1
y - 460 + y = 1280
2y = 1280 + 460
y = 1740/2
y = $870

Now,
x = 870 - 460
x = $410

Thus, the required amount we have is given as $410, as of the given condition.

Step by step solution
Need help ASAP PLEASE!!

Answers

Answer:

x=4

Step-by-step explanation:

-3(4x+3)

you need to break open the paranthesis

-3 times 4x equals to -12x. -3 times 3 equals to -9. That means that this expression is equal to -12x-9.

4(6x+1)

you need to break open the paranthesis

4 times 6x equals to 24x. 4 times 1 equals to 4. That means that this expression is equal to 24x+4.

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

move all variables to the left side and numbers to the right side

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

12x=48

x=4

You can add up the angles that are labeled(73,110,and 90 because of the right angle) and get 273.

For a quadrilateral, all of the angles add up to 360.

So, subtract 360-273.

You get 87.
