The average weight change is a loss of 8.75 pounds per person.
Step-by-step explanation:
This one was fairly simple, the 7 weeks have nothing to do with it. All you have to do is take the total amount of weight lost, 35 pounds, and divide it by the 4 people in the class. After the calculation, it equals an average loss of 8.75 pounds per person.
Answer:
x = 7.6°, so A = 18.8°
Step-by-step explanation:
What we need to know in order to utilize algebra is the total sum of all triangle's angle. It's 180°. So, we can write
25 + 17x - 1 + 3x - 4 = 180
20x + 28 = 180
20x = 152
x = 7.6°
Now what you need to do is substitute 7.6° into each expression 17x - 1 and 3x - 4.
