One way to solve is to set up a proportion. If the ratio of comedies to action is 4:3 (also can be written as the fraction 4/3) then you can set 4/3 equal to 20/x.


4/3 = 20/x

then cross multiply.  

4·x = 3·20


4x = 60  Then divide both sides by 4

x= 15

How much is 85cm longer than 1m ?
balandron [24]

1 meter has 100 CENTImeters.

now, 85cm is not longer than 1 meter clearly, because 100 cm > 85 cm.

so one can say, that is 1 meter is longer by 15cm instead.

100 -  85 = 15.

A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 p
lora16 [44]

Answer:

  • 425 min
  • $80

Step-by-step explanation:

<u>The equation to reflect the monthly plans:</u>

  • Plan A f(x) = 0.16x + 12
  • Plan B g(x) = 0.12x + 29

<u>We need to find the value of x when f(x) = g(x):</u>

  • 0.16x + 12 = 0.12x + 29
  • 0.16x - 0.12x = 29 - 12
  • 0.04x = 17
  • x = 17/0.04
  • x = 425 minutes

<u>The cost is:</u>

  • $0.16*425 + $12 = $80
