A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
Answer:
Step-by-step explanation:
The zeros of a function are where it crosses the x axis, so just find the coordinates for the x intercepts.

Answer:
n=−5
Step-by-step explanation:
n−4−3n=3n+6−3n
−2n−4=6
Step 2: Add 4 to both sides.
−2n−4+4=6+4
−2n=10
Step 3: Divide both sides by -2.
−2n
/−2
= 10
/−2
n=−5
Answer: 
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes = 
The probability that the upturned faces of the three dice are all of different numbers = 

The probability that the upturned faces of the three dice are all of different numbers is
.
