Step-by-step explanation:
you are "hiding" some more information (like how much they made together).
without that we cannot calculate the actual values.
all I can do is set up the equations expressing the given relations between the parts of the total :
a = amount Alberto made
b = amount Benjamin made
c = amount Carlota made
b = 3×a
c = 2×b = 2× 3×a = 6×a
that's it.
your see ? now we need something that "ties" all 3 together, an equation of all 3 variables, where we can use the first 2 equations (by substitution) and then solve for the remaining third variable.
and that is missing.
if it is something like "together they made x", then we would have
a + b + c = x
a + 3a + 6a = x
10a = x
a = x/10
b and c we get then from the first 2 equations by simply using the calculated value of a :
b = 3×(x/10) = 3x/10
c = 6×(x/10) = 6x/10 = 3x/5
-0.025 x 40=1
hope it help
4,800 that’s the answer for your equation
Answer:
Division
Step-by-step explanation:
PEMDAS
Parenthesis
Exponents
Multiplecation
Division
Addition
Subtraction
You have both exponents and parenthesis, so your third step would be multiplecation, but you don't have that, so it would be division.
Answer:
i^223 = -i
i^113 = i
i^82 = -1
i^48 = 1
Step-by-step explanation:
These are rules of i.
i^1 = i
i^2 = -1
i^3 = -i
i^4 = 1
You just have to apply this to the powers you are given.
