Use cross products to determine which are valid proportions. 47 and 10747.5
Proportion
Not a Proportion
23 and 9/12
318 aná 81141
18 8 and 914
715 and 2720

18/8 and 9/4, 4/7 and 10/17.5: PROPORTION.

2/3 and 9/12, 7/5 and 27/20, 3/8 and 6/141: NOT A PROPOTION :) Hope this help

Step-by-step explanation:

it is probably the graph on the bottom right.

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
