Answer:
<u>Josie will earn $13.75 and her brother Sean will earn $16.25</u>
Step-by-step explanation:
Given that For every $5.50 that Josie earns, her brother earns $6.50.
Tuesday, they earned $30.00
Using the ratio and the proportional
Josie : Sean : Total
5.5 : 6.5 : 12
x : y : 30
So, x = 5.5 * 30/12 = 13.75
And y = 6.5 *30/12 = 16.25
<u>So, Josie will earn $13.75 and her brother Sean will earn $16.25</u>
Let the two consecutive numbers be 2n and 2n+2
The sum of these numbers in 2n + (2n+2).
Hence
2n + (2n+2) = 34
4n + 2 = 34
4n = 32
n =8.
8 wks
3x( x+5) (x+4)
3x^3 + 27x^2 + 60x.
Factor out the greatest common factor
3x( x^2 +9x+20)
Now factor inside the parentheses
What two numbers multiply to 20 and add to 9
5*4 = 20
5+4 =9
-4 i believe is the answer
