Ineed some with i don't think any of these answers are correct so i don't know what to do. 3*10 = 30 9*10^4 = 900,000 see i was thinking it would be "3*10 is 3,000 times smaller than 9*10^4" , but i checked my work with 30*3,000 and got 90,000 instead of 900,000 someone i think the problem is actually broken.

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
