Answer:
$3.00
Step-by-step explanation:
Let p = the cost of a pack of pencils
and b = the cost of a binder
Then we have two simultaneous equations.
(1) 2p + 3b = 21.00
(2) 5p + 2b = 25.00
1. Multiply each equation by numbers to give one of the variables the same coefficient.
Multiply (1) by 2 and (2) by 3.This gives
(3) 4p + 6b = 42.00
(4) 15p + 6b = 75.00
2. Subtract (3) from (4)
This gives
(5) 11p = 33.00
3. Solve equation (5) for p
Divide each side by 11
p = 3.00
Each pack of pencils costs $3.00.
Answer with explanation:
1.Mean of a Data set


2. Range = Maximum value in two conferences - Minimum value in two conference
= 12 - 0
=12
The mean number of wins for teams from the two conferences is 7.65.
The range in wins is 12.
Answer: 1.875 is a rational number because it can be represented as a ratio or a fraction.
Answer:
600
Step-by-step explanation:
Given
equation t = 6n
n is term number
we have to find 100th term.
Thus, term number is 100
substituting 100 in place of n in equation t=6n , we can find the value of 100th term
t = 6*100 = 600
Thus, 100th term is 600.
