The equation we use here is:

x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.
Simplify:

To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.
When we plug the 20 into the equation as x:

So he needs to play at least 30 games in order to get his score to 94%.
35 out of 100 play soccer...
35/100 = 7/20 = 0.35 = 35%
I think it would take 24 hours or 10 hours
explanation: if you have 4 hours from Erin, and 6 hours from Cathy, it’ll most likely be 10 hours because you’re trying to find out the total amount. (keyword: together & how many)
3:8 - 3:8
8:6 - 4:3
4:8 - 1:2
I would say that the answer is 1:2
I’m not sure about number 9. But number 10 is answer C. This is because there are two sides to a coin, so you are equally likely to land on heads as you are tails. So you take 64 and divide it by 2, and get the answer 32.
