Answer:
15%
Step-by-step explanation:
The quantities must be in the same units
Using the conversion
I hour = 60 minutes, then
3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.
Thus
× 100% = 
= 15%
The answer would be 10.8
9/5=x/6
Cross multiply
5x=54
Divide by 5
x=10.8
Answer:
The roots can be seen from the graphs as - 4 and +4
The equation is :
x² - (sum of roots) + (product of roots)
Equation is x² -16
I hope you got it
Just take both sides multiply by 2 then divide 3
Answer:
D 18

Let r = red pens
b =5r
g = 3r
The total number of pens

Substitute
r + 5r+ 3r
Combine like terms
9r
The number of pens must be a multiple of 9
18 is a multiple of 9
