Which sets of ordered pairs show equivalent ratios?. Check all that apply. (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

(2, 2) ; (4, 4) ; (6, 6)

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Step-by-step explanation:

(1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Evaluating the ratio of each pair :

(1, 2) = 1/2 = 0.5

(2,3) = 2/3 = 0.67

(4, 7) = 4/7 = 0.57

(2,2) = 2/2 = 1

(4, 4) = 4/4 = 1

(6, 6) = 6/6 = 1

(3, 1) = 3 /1 = 3

(4, 1) = 4 / 1= 4

(5,1) = 5 / 1= 5

(4, 1) = 4 / 1 = 4

(8, 2) = 8/2 = 4

(12,3) =12/3 = 4

(2, 1) = 2/1 = 2

(4,3) = 4 / 3 = 1.33

(5, 4) = 5 / 4 = 1.25

Pairs with equivalent ratios :

Ratio of 1;

(2, 2) ; (4, 4) ; (6, 6)

Ratio of 4:

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
