Answer:
g = 1000K
Formula: Multiply the amount of kilograms with 1000 to convert it into grams
Step-by-step explanation:
Kilo stands for 10³ or 1000. So, a kilogram means one thousand grams. This means that if you ever want to get back to grams from kilograms, all you need to do is multiply the number of kilograms by 1,000.
Number of grams = Number of kilograms x 1000
g = 1000K

Answer:
27 - 50k
Simplify
1. Distribute
-5 ( 1 + 2k ) - 8 ( -4 + 5k )
-5 - 10k - 8 ( -4 + 5k )
2. Distribute
-5 - 10k - 8 ( -4 + 5k )
-5 - 10k + 32 - 40k
3. Add the numbers
-5 - 10k + 32 - 40k
27 - 10k - 40k
4. Add the same term to both sides of the equation
27 - 10k - 40k
27 - 50k
Answer:
first thing, take 3 pairs of equations and in each pair, make any one variable's coefficient equal to the coefficient of the same variable in the other equation and subtract the equations.
you will get 3 different equations:
x+y = 1
- 4x - 21z = 72
-x + 3z = -10 (simplified)
now take the value of x and y from equation 2 and 3 in terms of z and substitute x and y with those values
y = (72 + 21z)/-4
x = 3z + 10
as x + y = 1
you will get z = -4 after sloving the equation
now you have the value of one of the variables..
now we will substitute z in the equations to get the other variables
x = 3z + 10
x = 3(-4) + 10
x = -12 + 10
x = -2
Now y:
72+21(-4)/-4
(72 - 84)/-4
-12/-4
y = 3
so,
z = -4
x = -3
y = 3
