Answer:
Step-by-step explanation:
a/(b+c) < 2a/(a+b+c)
b/(a+c) < 2b/(a+b+c)
c/(a+b) <2c/ (a+b+c)
so a/(b+c)+b/(a+c)+c/(a+b) <2(a+b+c)/(a+b+c)=2
Step-by-step explanation:
Well 3/5 is left.
20 × 5 = 100
She did 40% because 2/5 = 4/10
So if 20 × 3 = 60 the there is 60% left
Answer:
22
Step-by-step explanation:
5/3=x-4/2
10=x-12
x=22
Answer:
y = 5x + 25
Explaination:
To get the equation of a line, first get the slope of the line.
Slope = (change in y)/(change in x)
= (60-30)/(7-1)
= 30/6
= 5
Now use one point in the line (4,45) and a general point (x,y).
Slope = (change in y)/(change in x)
5 = (y - 45)/(x - 4)
5(x - 4) = (y - 45)
5x - 20 = y - 45
y = 5x -20 + 45
Answer:
There are 96 boys in the soccer league.
Step-by-step explanation:
You multiply 160 by 60%, which is also 160*.6.
160*.6=96
