Answer:
Step-by-step explanation:
price of 1 pen= $ 2
price of 1 pencil= $1
total money spent= $12
Let the number of pen be a and number of pencil be b.
2 a + b = 12 ----------------Equation 1
We have, she bought 3 more pens than pencils
a - b = 3 ------------------ Equation 2
Equation 1 +Equation 2,
2 a + b + a - b = 12 + 3
3a = 15
a = 5
Substituting in equation
5 - b = 3
b = 2
Number pencils Ava bought = 2

Answer:
x = 9
27, 45, 54
Step-by-step explanation:
The mean of 6x, 3x and 5x = 6x + 3x + 5x / 3 = 14x / 3 = 4 2/3x
The mean of 40, 50 and 36 = 40 + 50 + 36 = 126/3 = 42
4 2/3x = 42
x = 42÷14/3 = 42 * 3/14 = 9
6x = 54
3x = 27
5x = 45
Least to greatest order: 27, 45, 54
Hope this helps :)
