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
Answer:
32% of the tub will be filled after 8 minutes. Hope this helps!
Step-by-step explanation:
4x8= 32
A=6
b=24
c=33
don't put x..x'2 ok when you solving by this
Answer:
b....j..j.jm..e.e.e i didnt get it
Answer:
200 miles were driven
Step-by-step explanation:
We know that 
represents the cost of renting a car
Where m represents the number of miles driven
If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.
