Answer:
(3,4)
Step-by-step explanation:
The system of equations is:
x+6y=27
7x-3y=9.
I looked up "metodo de igualacion". It is basically American for doing substitution.
However, the only difference is you are asked to solve both equations for a variable.
The first equation looks easy to solve for x. So I'm going to solve both equations for x.
x+6y=27
Subtract 6y on both sides:
x =-6y+27
7x-3y=9
Add 3y on both sides:
7x =3y+9
Divide both sides by 7:
x =3/7 y +9/7
So both equations are solved for x. You want to find when the x's are the same because you are looking for a common amongst the lines given.
So we have
-6y+27=3/7 y +9/7
I hate the fractions honestly so I'm going to multiply both sides by 7 so they will no longer be for now:
-42y+189=3y + 9
Now add 42y on both sides:
189=45y+9
Subtract 9 on both sides:
180=45y
Divide both sides by 45:
4=y
If 4=y, then y=4.
So now once we have obtain 4 for y, we will use one of the equations given along with it to find x. Just choose one. Choose the easier looking one to you.
I like the x=-6y+27 with y=4.
So replace y with giving you:
x=-6(4)+27
x=-24+27
x=3
So the solution is (x,y)=(3,4).
x=3 and y=4.
Answer:
f
Step-by-step explanation:
The value of p(cc and tc) is 0.1173
The distribution of the replies is 0.12, as shown by the two-way table.
We've done that.
520 randomly chosen individuals from the teen, young adult, and adult age groups were asked about their preferred musical genres by the researcher.
The distribution of the answers is shown in the two-way table.
There are 61 teenagers in the country.
seeing as how this is only one of 520,
The probability formula?
P(E) = (Number of favorable outcomes) = Probability of an Event (Sample space).
61/520=0.1173
We calculate 0.1173 by dividing 61 by 520 and rounding to the next hundredth to obtain 0.12.
Thus the value of p(cc and tc) is 0.1173.
