X = the brother
c = carly
c = 3x
c + x < = 24
now we sub
3x + x < = 24
4x < = 24
x < = 24/4
x < = 6 ...oldest age the brother can be is 6
Answer: $12.57 hope this helps
Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)


Answer:
3
Step-by-step explanation:
4 1/2 + 3 1/3 + 2 + 2 1/6
= 4 3/6 + 3 2/6 + 2 + 2 1/6
= 4 + 3 + 2 + 2 + 3/6 + 2/6 + 1/6
= 11 + 6/6
= 11 + 1
= 12
There are 4 numbers, therefore average = 12 ÷ 4 = 3
