Answer:
2280 minutes.
Step-by-step explanation:
Time spent each week in lessons = (Lessons per week)(Time per lesson)
= (6)(38)
= 228 minutes/week
Time spent in a 10-week period:
10 weeks * 228 minutes/week
= 2280 minutes
Use conversion factors to determine the time in the desired units (i.e. Hours, seconds, etc.).
Hope this helps!
Answer:
x=40
Step-by-step explanation:
Because every triangle's angles add up to 180 degrees, you know 3x+x+20=180. Since 3x and x are like terms, you can add them to get 4x. 20 and 180 are also like terms. However, to move your 20 to the side of 180, you need to subtract it. So you have 4x=160. To get x by itself, you divide 4x and 160 by 4. 4x/4 is x, and 160/4 is 40. So your answer is x=40.

=8y + 6y - 29y + 15
Step-by-step explanation:
The length and width of the television could be any two numbers whose product is 70.
Answer:
The second number would be 8 or 16
Step-by-step explanation:
Let x be the unknown number,
Since, first number = 17,
So, the difference between x and 17 = |17 - x |
According to the question,
|17 - x | = 9
17 - x = ± 9
17 - x = 9 or 17 - x = -9
17 - 9 = x or 17 + 9 = x
⇒ x = 8 or x = 26
Hence, the second number would be 8 or 26.
