Answer:
las fracciones decimales son:
21/10 = 2,1
439/100 = 4,39
34/10 = 3,4
35/1000 = 0,035
851 / 1000 = 0,851
Step-by-step explanation:
Toda fraccion cuyo denominador (el numero de abajo) es multiplo de 10 es considerada una fraccion decimal. No importa si el numerador es mayor al denominador. Justamente el sistema decimal fue concebido para facilitar la multiplicacion y division de los numeros por algun multiplo de 10.
Hi there!
To solve this equation, I first would like to warn you about the long answer I am about to post for you. I'll be putting in very detailed steps for you, showing you how to simplify and distribute numbers, etc. :)
Let us solve your equation step-by-step.
Step 1) Simplify both sides of the equation.
To simplify this, we will...
4 + (-2) (x) + (-2) (7) = (3) (x) + (3) (5)
4 + - 2x + - 14 = 3x + 15
(-2x) + (4 + - 14) = 3x + 15
Now, we combine Like Terms...
-2x + - 10 = 3x + 15
-2x - 10 = 3x + 15
Fwew! That was probably going to be the longest step here!
Step 2) Subtract 3x from both sides.
- 2x - 10 - 3x = 3x + 15 - 3x
- 5x - 10 = 15
Step 3) Add 10 to both sides.
- 5x - 10 + 10 = 15 + 10
- 5x = 25
Step 4) Divide both sides by -5.
-5x/-5 = 25/-5
So, our final answer is x = -5.
Hope this helps!

Step-by-step explanation:
The equation representing the elevation of Grand Lake after x number of days, given a decrease of 3 inches per day, is Elevation = 648 - 0.25x, where 0.25 is the daily loss rate in feet and x represents the number of days.
The subject of this question is the application of linear equations to real-world problems, specifically in the context of environmental changes. Given the initial elevation of Grand Lake and the daily rate of water level decrease, we can write an equation that represents the elevation of the lake's surface after x days.
The initial height of the lake is 648 feet. Every day, the lake elevation drops by 3 inches. However, our rate is given in inches and the initial elevation is in feet. We should convert the rate from inches to feet. Since there are 12 inches in a foot, 3 inches is equal to 3/12 = 0.25 feet.
So after one day, the lake would be at 648 - 0.25 = 647.75 feet. After two days, the lake would then be at 648 - 2(0.25) = 647.50 feet, and so on. In general, after x days, the elevation of the lake would be 648 - x(0.25)
Therefore, the equation we are looking for is: Elevation = 648 - 0.25x
