Answer:
Three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
Step-by-step explanation:
An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.
First equivalent ratio
You can divide the numerator and denominator by 3. You get 2/3

Second equivalent ratio
You can multiply the numerator and denominator by 2. You get 12/18

Third equivalent ratio
You can multiply the numerator and denominator by 3. You get 18/27

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
Answer:
See below.
Step-by-step explanation:
The addition method is a good choice in this case since you have x in one equation and -x in the other equation, and x and -x add to zero, eliminating x.
x - 5.5y = -14
-x + 2.6y = 8.2
Add the equations. x and -x ad to zero, eliminating x. Then solve for y.
-2.9y = -5.8
Divide both sides by -2.9
y = 2
Substitute 2 for y in the first original equation, and solve for x.
x - 5.5y = -14
x - 5.5(2) = -14
x - 11 = -14
x = -3
Solution: x = -3; y = 2
Since the coefficients of y in the two original equations are not opposites, the addition method would not be the best method to use to solve for y first.
Do you have more information. Is there multiple choice?
