Since both the length and the width are tripled, the area will be nine times larger. To counter this, divide by nine. 108/9=12 Divide this by 2 to get one length and one width. You get 6. 1+5=6 and 1 is 4 smaller than 5, so the width of this rectangle is 1 cm and the length is 5 cm.
Answer:
it was decreased by 67%
Step-by-step explanation:
Answer:
she will have to work 11 hours
Step-by-step explanation:
221 divided by 13=17
therefore she makes 17 dollars an hour
so 187 divide by 17 = 11
Answer:
Step-by-step explanation:
The two equations given represent two straight lines in 2-D graph.
The two lines will not intersect if they are parallel.
Hence the two equations will not have solution if the lines are parallel and not coincident.
The condition for 2 lines given by the equations :
ax+by+c=0
dx+ey+f=0 to be parallel but not coincident is:
here a=2 b=-3k c=-1 d=4 e=k+2 f=-5
But also:
Hence the value of k is -2/7.

Answer: B = 10A + 8</h3>
===========================================================
Explanation:
This is something you would do through trial and error to check each answer choice
--------------
We can cross off A = 10B since
A = 10B = 10*(6,007,058) = 60,070,580
but that's not what A is actually equal to (it should be 600,705)
---------------
We can also cross off A = 100B + 58 because,
A = 100B + 58
A = 100*(6,007,058) + 58
A = 600,705,800 + 58
A = 600,705,858
But that doesn't match with A = 600,705 either
-----------------
Now let's try the third equation
B = 10A + 8
B = 10(600,705) + 8
B = 6,007,050 + 8
B = 6,007,058
That matches with what your teacher gave you. So this confirms we have the correct equation.
-----------------
I'll let you check the remaining two. You should find that they don't work out.
