<u>3. Simplify</u>:
- 4.25n + 5/4n = 4.25n + 1.25n = 5.5n
- 3/2p - 2p = 1.5p - 2p = - 0.5p = - 1/2p

8 would be more times than it's of pyramid b then A
Answer:
x = 5, x = 
Step-by-step explanation:
Given
+
= 3 
= 
= 
=
( cross- multiply )
10(x² - 6x + 8) = 3(2x² - 10x + 10) ← distribute both sides
10x² - 60x + 80 = 6x² - 30x + 30 ← subtract 6x² - 30x + 30 from both sides
4x² - 30x + 50 = 0 ( divide through by 2 )
2x² - 15x + 25 = 0 ← in standard form
(2x - 5)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
2x - 5 = 0 ⇒ 2x = 5 ⇒ x = 
x - 5 = 0 ⇒ x = 5
Answer:
19958400 ways
Step-by-step explanation:
As the question involves arrangement, permutation will be used.
P(n,r) = n! / (n-r)!
Here
n=12
and
r = 8
So,
P(12,8) = 12!/(12-8)!
= 12!/ 4!
=19958400 ways
Therefore, the 8 objects from 12 can be arranged in 19958400 ways ..
Given that the cost of b burgers and h hot dogs is given by 3.25b + 2h.
Therefore, the cost of 4 burgers and 6 hot dogs is given by 3.25(4) + 2(6) = 13 + 12 = $25.
