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
Answer:4x plus 2 might be the,answer

Answer:
The correct answer is:
44% (B.)
Step-by-step explanation:
number of times flipped = 50 times
number of times red landed face-up = 22 times
∴ frequency of chip landing with red side face up = (number of times red landed face-up) ÷ (number of times flipped) × 100
= (22 ÷ 50) × 100 = 44%
Answer:
3/4 or 75%
Step-by-step explanation:
