Answer:
Your friend is kayaking faster.
Step-by-step explanation:
The way to approach this answer is by putting one of them in terms of the other. So that both are in terms of the same time. If you kayak 63 feet in 12 seconds how many feet do you kayak in 2 seconds? Simply divide by 6. 63/6 = 12/6. So, in 2 seconds (12/2) you kayak 10.5 feet (63/6). But your friend kayaks 21 feet in the same time... so he's going faster.
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
Answer:
27 females are in the class
Step-by-step explanation:
Spilt 30 into 10 (30 divided by 10) and then you get 3. The number of males in the class is 3. Now subtract 30 from 3 and you get 27. Therefore, there are 27 females in the class.
2t > 324
divide each side by 2
2t/2 > 324/2
t > 162
12y >= 1
divide each side by 12
12y/22 >= 1/12
y >= 1/12
x/9.5 < 11
multiple each side by 9.5
x/9.5 * 9.5 < 11 * 9.5
x < 105.5
