Answer:
Sarah took home 30 pies
Step-by-step explanation:
Given
Total remaining pieces of pies after bake sale left with Sarah = 35
Her neighbor took 1/7 of the remaining pies
Her neighbor took 1/7 * 35 = 5 pies
Hence, pieces of pies left with Sarah = 35 - 5 = 30
Step-by-step explanation:
x°+118°+34.6°=180°...(sum of angles in a ∆)
x°+152.6°. =180°.....(sum of angles in a ∆)
x°. =180°-152.6°
x°. =27.4°

Answer:
b/c+30
Step-by-step explanation:
H = 7
l = w + 6
V = 280
V = lwh
Plug in what we know:
280 = (w + 6)(w)(7)
Distribute W into the first parenthesis:
280 = (w^2 + 6w)(7)
Distribute 7:
280 = 7w^2 + 42w
Divide 7 to both sides:
40 = w^2 + 6w
Subtract 40 to both sides:
w^2 + 6w - 40 = 0
Factor:
(w - 4)(w + 10) = 0
Therefore, w = 4.
Plug this back into the equation for the length:
l = w + 6
l = 4 + 6
l = 10
