Answer:
5/9
Step-by-step explanation:
The equation that you put is correct
The answer is 4 hours
p -<span> the programming time
</span>c - time spent on commercials
<span>A radio station broadcasts programs and commercials 20 hours everyday:
p + c = 20
</span><span>The ratio of the time spent on commercials to the programming time is 1:4.
c : p = 1 : 4
p = c * 4 : 1
p = 4c
p + c = 20
p = 4c
_____
4c + c = 20
5c = 20
c = 20 : 5
c = 4h</span>
17.8 multiplied by 2 is 35.6
9.5 multiplied by 2 is 19
Now you take both of them and add them together.
35.6 + 19 = 54.6
Your answer should be 54.6 inches of ribbon.
Hope this helps.
