Justify "<span>x2 = 25 is {±5}"

First, please write x^2, not x2.

</span><span>x^2 = 25; solve for x.  Take the sqrt of both sides.  Must write "plus or minus " in front of the sqrt of 25:

So we have to put the value of 1:3 in a ratio

1 : 3
= 3:y

Ask yourself what do I have to multiply one by to get three ( the answer is three)
Because one side is multiplied by three, you have to multiply the right hand side by three to get y
3*3 is 9

Therefore, the y for 3 hours is 9

Then, we have to make another ratio
1:3
= 5:x

Ask yourself what do I have to multiply by one to get five (the answer is five)
So you multiply the other side by five as well
3*5=15

Therefore, the y for five hours is 15

AnnZ [28]

number of times flipped = 50 times

number of times red landed face-up = 22 times

= (22 ÷ 50) × 100 = 44%
