Answer:
4%
Step-by-step explanation:
We have been given that Jake is 25 years old. Next year, he'll be 26 years old.
To find the percentage increase in Jake's age from last year, we will use percentage decrease formula as our original value is less than new value.
Now let us substitute our given values in above formula.
Since our answer is a negative number then this is a percentage increase.
Therefore, there is 4% increase in Jake's age from last year.
Answer:

Step-by-step explanation:
X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!

Answer:
<em>2.5 hours</em>
<u>Skills needed: Speed, distance, time problems</u>
Step-by-step explanation:
1) We are given speed and distance, and have to find out the the time (in hours).
- In terms of units, everything is matched up (Since distance and speed use kilometers, and speed and time use hours).
- Time is always the distance you travelled (how far) divided by how fast you travelled (the rate/speed)
---> We can use the formula for time:
t= time
d=distance
r=rate/speed
2) Now, let's plug in for distance and rate.
--->
2.5 hours is the answer.
