Answer:
the answer of the question is C because 1/2=.5
Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.
Answer:
2,000 miles
Step-by-step explanation:
We are given:

This can be rewritten as:

This is representative of a unit rate, as we have a
in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:


This can rewritten as:

Therefore, there are 2,000 miles in 4 inches.
-
We can check our solution by simplifying the fraction
by dividing both
and
by
to see if we achieve the unit rate:

Since this is in fact the unit rate, our solution is correct!
Answer:120
Step-by-step explanation:
132/11= 12
it means each 10 percent is = to 12
12*10 = 120
