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
Step-by-step explanation:
The positive factors of -3 are 3 and 1
There is also -3 and -1
Here you go! Please mark me brainliest pls pls
We can find this answer by remembering the laws about opposite angles and their sums. We know that since 1 and 2 are opposite angles, they must be equal to each other. Therefore, we can set them equal to each other to solve for x.
<u>Solving For x</u><u />
x+5=6x-30
-x -x
5=5x-30
+30 +30
35=5x
/5 /5
7=x
Now that we know x=7, we can substitute that value in for x in the angle measurements.
<u>Angle 1</u><u />
x+5
7+5=12
<u>Angle 2
</u><u /><u />6x-30
6*7-30=12
We know that we have the correct x-value because both angles are equal. Therefore, we know that the measure of both angles is 12 degrees.
This worker would take 200/8=25 hours, since he makes eight computers an hour and needs to spend enough time to make 200 computers. C is the correct answer.
