Step-by-step explanation:
Shes wrong because she did it in 3 hours which means she would have made 3 cards and not 9.
We have to set up 2 different equations if we are to solve for 2 unknowns. The first equation is x = y + 4. One number (x) is (=) 4 more than another (y + 4). Since we have determined that x is larger (cuz it's 4 more than y), when we set up their difference, we are going to subtract y from x cuz x is bigger. The second equation then is

. In our first equation we said that x = y + 4, so let's sub that value in for x in the second equation:

. Expand that binomial to get

. Of course the y squared terms cancel each other out leaving us with 8y + 16 = 64. Solving for y we get that y = 6. Subbing 6 in for y in our first equation, x = 6 + 4 tells us that x = 10. Yay!
If you switch it around, it'll be: 1,707 - 264
Subtract:
1,707 - 264 = 1443
Answer = 1,443

I think the first answer is 41/100
Explanation:
I worked out how likely you would be to get a green marble based off of the answers, then added them together and divided by 3
2/5 = 40/100
9/16 = 50/100
3/9 = 33/100
40+50+33 =123
123/3 =41
Then for the second answer I think it’s 50% (1/2)
Answer:
2
Step-by-step explanation:
2 2/3=8/3
8/3*3/4=8/4=2
