Step-by-step explanation:
Total marbles = 9 + 4 + 3 + 2 = 18
Probability of both red marbles = 3 / 18 = 1/6
Answer:
$6 = cost of small box
$8 = cost of large box
Step-by-step explanation:
Let s = cost of small box
l = cost of large box
(1) 12s + 3l = 96 (2) 6s + 6l = 84
Multiply by -2 <u> -24s - 6l = -192</u>
-18s = - 108
s = $6 = cost of small box
12(6) + 3l = 96
72 + 3l = 96
3l = 24
l = $8 = cost of large box
Answer:
7 and 8

Answer:
Option C. X=A/4
Step-by-step explanation:
we know that
The area of the rectangular post it note is equal to

where
L is the length
W is the width
In this problem we have


substitute

solve for x
That means ----> isolate the variable x
Divide by 4 both sides
