here are three fractions: 2/3, 4/5,6/9. Two of these fractions are equivalent to each other. Which two? Explain your reasoning in a complete sentence.

The two fractions equivalent to eachother are 2/3 and 6/9

Step-by-step explanation:

These fractions are equivalent because 6/9 can be reduced into 2/3. Also 6 is a multiple of 2 and 9 is a multiple of 3.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
