Hi,
8t + 6t + 7y = (8 + 6)t + 7y = 14t + 7y.
The distance that Harold swim in 5 hours should be 16 km.
Given that,
- Harold swam 6 2 ÷ 5 km in 2 hours.
- And, the number of hours given is 5 hours.
Here we assume the distance be x
So,
=6.4
Now
2x=(6.4)(5)
2x=32
Now Divide by 2 on both sides
Thus,
X=16 km
Therefore, we can conclude that the distance that Harold swim in 5 hours should be 16 km.

To find the discount rate you must first, multiply the RATE by the original price. Then to find the sale price, subtract the DISCOUNT from the original price.
Okay, so Angelo had a dollars and spent 1/3 of that. So he spent 1/3a
Then, the amount he has left can be denoted as: (a - 1/3a)
Jimmy had j dollars and spent 1/2 of it:
So the amount he has left can be denoted as (j - 1/2j)
Since jimmy had more money left, you would subtract the amount angelo has from the amount that jimmy has left.
So: (j - 1/2j) - (a - 1/3a).
Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares
