Where 1/4 represents Bob and 1/6 represents Ted...
1/4x + 1/6x = 1
Multiply the two so there is no fraction by the GCF of 12. 
3x + 2x = 12
Add 3x and 2x.
5x = 12
Divide by 5.
x = 12
Plug this value in.
With that, the answer is 2 hours and 24 minutes with x = 12 meaning 144 minutes.

SpyIntel [72]

Answer:

1,231 people

Step-by-step explanation:

1,256 people currently subscribe. $0.25 is 5 nickels, and for every nickel the price is raised, 5 people unsubscribe. That's 1 person per cent. 25 people will unsubscribe for every $0.25 the price is raised. 1,256-25 is 1,231, so 1,231 people will continue to subscribe after the price increase.

Help!!!!!!!!!find the equation of the linear function q(16)=1 that is parralel to f(x)=1/3x+39
kkurt [141]

Answer:

q(x)= \frac{1}{3} x -\frac{13}{3}

Step-by-step explanation:

So you have (16, 1)

When two linear functions are parallel, they have the same slope.

So function q also has a slope of 1/3x. You have a set of points so you can plug them in a slope intercept equation to find b.

y= mx+b

m= slope

y= y-intercept

1= 1/3(16) +b

1 - (16/3) = b

b= -13/3

so then, y= \frac{1}{3} x -\frac{13}{3}
