Nataly [62]

Answer: 3 hours

Step-by-step explanation:

From the question, we are informed that WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music.

Hours used for commercial:

= 1/5 × 10

= 2 hours

Hours used for music:

= 1/2 × 10

= 5 hours

Hours left for news will be:

= 10 hours - 2 hours - 5 hours

= 3 hours

Help Please.<br><br> If 7m - 3 = 53. What is the value of 11m + 2?
Pachacha [2.7K]

Answer:

90.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
