Answer:
49
Step-by-step explanation:
devaughn= x+15
sydney= x
set an equation adding both their ages
x+x+15=113
2x+15=113
subtract 15 from both sides
2x=98
x=49
sydney is 49
its bella saves more per chore than sweet tea, because 3.5 x c = the amount of chores bella does. Add 11 to that, and she will get more than Sweet Tea. for Sweet tea, one chore saves her twelve dollars. For Bella, one chore saves her more.

Answer:
option 4 ⇒ 236 lb.
Step-by-step explanation:
Best explanation of the question is as shown in the attached figure.
we will use the parallelogram method to calculate resultant force.
to get the length of the resultant force ⇒ use the cosines law
The cosine law is a² = b² + c² - 2 * b * c * cos (∠A)
Applying at the question where b = F₁ , c = F₂ and ∠A = ∠x
Given that F₁ = 100 pounds , F₂ = 150 pounds and ∠x = 180° - 40° = 140°
∴ (Resultant force)² = 100² + 150² - 2 * 100 * 150 * cos (∠140) = 55481
∴ Resultant force = √55481 = 235.54 ≅ 236 pounds
The answer is option 4 ⇒ 236 lb.
