Answer:
Well, I'm not really sure what to do, but if you just need the numbers to multiply to get the latter numbers in the question they are: 10/11 (for the first question) and 81/80 for the second.
Step-by-step explanation:
For Question #1: You just multiply 5/11 by two to get the number that 1/2 has to multiply to get 5/11. And 5/11 * 2 is 10/11. So I guess the answer is 10/11...
For Question #2: The common denominator for them both is 180, and 4/9 times 81/ 80 is what 80/180 (4/9) has to multiply by to get 81/180.
I used the equation 4/9x=9/20
Multiplied the 9 and then divided by 4 to get the answer, which was 81/80.
***I also noticed, that 1/2 is 1/22 away from 5/11, and 4/9 is 1/180 away from 9/20.
Hope this helps!
Answer:
f(2) = -4
Step-by-step explanation:
for f(2), plug it into f(x)=3x-10
3(2)-10
6-10
-4
f(2) = -4
Answer:
A rational number is normally number that can be expressed in the form of p/q where q ≠ 0. But, 
cannot be expressed in the form of p/q. So. this means that

You need to find the unit rate of 3 : 1800 first by dividing 1800 and 3
1800 ÷ 3 = 600
So this means for every 1 pound bag it covers 600 square feet. You now need to multiply 600 and 4 to see how many square feet 4 pounds cover.
600 × 4 = 2400
So each 4 pounds covers 2400 sq ft. Now you have to divide 8400 and 2400 to find how many bags of 4 pounds you need
8400 ÷ 2400= 3.5
You need 3.5 bags of 4 pounds.
Technically you would need 4 bags because you’d have to round it up.
Hope this helps you!! :)
