12/14 can be simplified, and that would be an equivalent ratio. Divide 12 and 14 both by 2, and then you get 6/7.
Another equivalent ratio is 120/140. To get this ratio, I merely multiplied both the numerator and denominator of the ratio by 10.
You can get an infinite amount of equivalent ratios for 12/14. All you have to do is make sure that whatever you multiply one part of the ratio by, you have to multiply the other part of the ratio by the same thing.
A final example is 60/70. I just multiplied both 12 and 14 by 5.
Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x
Answer:
the answer is 13. 6 is the correct answer
Let x = your number.
5x = x^2 - 14. To figure out the number, we have to first subtract 5x from each side.
0 = x^2 - 5x - 14. Factor.
0 = (x - 7) (x + 2). Set both terms to 0.
(x - 7) = 0. Add 7 to each side.
x = 7. You're looking for the negative value so this isnt the right one.
Set the other term (x + 2) equal to 0
(x + 2) = 0. Subtract 2 from each side.
x = -2
The negative solution for your number is -2
Sound, earthquakes, the brightness of stars, and chemistry, such as pH balance, a measure of acidity and alkalinity, are all instances of this.
