Doesn't match.
2. Subtract
from the previous value:

Doesn't match.
3. Divide the previous value by 2:

Doesn't match.
4. Multiply the previous value by 2:

DOES WORK!
Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
Answer:
87%
Step-by-step explanation:
We need to convert this fraction to a decimal. To do that, we divide 6 by 7. That gets us 0.85714285714. We need to round that to the nearest hundredth. That gets us 0.86. Now, we need to convert this to a percentage. To do that, we move the decimal two places to the right. That gets us 86. She rode her bike 87% of the days this week.
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>The equations are:</u>
<u>Add up the equations to eliminate y and solve for x:</u>
- x - y + 2x + y = 2 + 13
- 3x = 15
- x = 15/3
- x = 5
<u>Now find the value of y:</u>
- y = x - 2
- y = 5 - 2
- y = 3
