20.8KGs equals 20L, what is 10.5 kgs in litres

Answers

y = k x

20.8 kg = 20L
10.5 kg = ?L

Independent variable (y) : 20.8 kg
Dependent variable (x) : 20L

Find k, or a number that will be multiplied to the dependent variable to produce the independent variable.

20.8 kg = k (20L)
20.8 kg ÷ 20L = k
k = 1.04

Use k to find the dependent variable in the second set of items.

10.5 kg = (1.04) x
10.5 kg ÷ 1.04 = x

The answer would be:
10.1L


What is the coefficient of z in the expression 3x + 2y + z?

Answers

the coefficient is 1. 1z = 1*z = z.

You are given the expression 3x + 2y + z

It is clear that coefficient of x is 3 and y is 2. But there is nothing written with z.

So what is the coefficient of z?

When there is no number written before a variable, then its coefficient is 1.

Coefficient is always muktiplied with the variable. So z = 1×z = 1z. But we generally do not write 1 before a variable.

So coefficient of z is 1.

okay so we have this question of the week thing and this week our answer is 47 so i need a algebra problem that equals 47 can someone please help me ?

Answers

Answer: 5 times 5 plus 11 plus 11

Step-by-step explanation:

Creating an algebra problem that equals to 47.

5 times 5 is 25

25 plus 11 is 36

36 plus 11 is 47

Answer:

The Sum of two numbers equals 47 and their difference is 25, What are the 2 numbers.

Step-by-step explanation:

okay so this is kinda confusing but ill try my best to explain it.

x+y=47

x-y=25 which turns into x+x+y-y=47+25. which simplifies to 2x=72 divide 72 by 2 and you get 36. so x=36. then its 36+y=47 subtract 36 from 47 to get y and you get 11. so y=11. so you final answer is 36+11=47.

i’m doing the same thing and don’t understand. my question is m/5+9=11

What is 3/5 plus 3/17 using benchmarks.

Answers

the best thing to do is to find a common denomiantor, and you can do this by listing the multiples.
5- 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85
17- 17 34 51 68 85 102

The lowest common multiple is 85, so you've got to multiply the first fraction by 17, and the second by 5.
3x17= 54, 5x17= 85 and 3x5= 15, 5x17= 85.
this then becomes 54/85 and 15/85, when you're adding fraction, you add the denominators- 54+15= 69, therefore, the fraction becomes 69/85
Hope this helps :)

Step-by-step explanation:

Use elimination to solve the system:
6x-4y=6
-6x+3y=0

Answers

6x and -6x cancel each other out.
You are left with -1y=6
Therefore, y=-6

6x-4(-6)=6
6x+24=6
Subtract 24 from both sides.

6x=-18
Divide both sides by 6
X=-3

Final answers: x=-3 y=-6
6x+4y=6
-6x+3y=0

7y=6
y=6/7

use one of the equations above i picked the first one
6x+4y=6
6x+4(6/7)=6
6x+24/7=42/7
6x=18/7
x=3/7
