Which of the following statements expresses a true proportion? O A. 14 : 6 = 28: 18
O B.3:5 = 12:20
O C. 42 : 7 = 6:2
O D. 2.3 = 3:2

B

Step-by-step explanation:

3 x 4 = 12

5 x 4 = 20

20 ÷ 4 = 5

12 ÷ 4 = 3

what does x eaqual

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
