Answer:
8 weeks
Step-by-step explanation:
p = 2w
p = total pieces = 16
then putting value in p = 2w
16 = 2w
divide by 2 on both side we get
16/2 = 2w/2
8 = w
where w is total weeks i.e 8
Answer:
C. 9 lbs.
Step-by-step explanation:
80 ounces = 5 pounds
64 ounces = 4 pounds
5 pounds + 4 pounds =
9 pounds / 9 lbs.
Answer:
The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).
Step-by-step explanation:
We have to solve the given quadratic equation of single variable t.
The equation is 16 = 2t + 0.25t²
⇒ 0.25t² + 2t - 16 = 0
⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}
⇒ 25t² + 200t + 400 - 400 - 1600 = 0
⇒ (5t + 20)² - 2000 = 0
⇒ (5t + 20)² - (20√5)² = 0
⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0
So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0
⇒ (t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0
⇒ t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)
