Distribute the negative sign to the 4x and 11 making it 3x+5y-4-4x-11 and combine like terms
Step-by-step explanation:
time ∝ number of door 1
time . ∝ 1/number of people. 2
compare equation 1 and 2
time . ∝ number of door / number of people
put k as constant
time = k number of door / number of people. 3
time =2. people=4 door = 10
putting in equation 3
2 = k (10)/(4)
2×4/10 = k
8/10 =k
4/5 =k
putting in equation 3
time= 4/5 number of door / number of people
now time =5 door= 25 people=?
5=4/5 (5)/ (number of people)
number of people =4/5 ×25/5
number of people= 4
Answer:
The angle 2pi/3 terminate in quadrant II
Step-by-step explanation:
Quadrant I ⇒ 0 < θ < (π/2)
Quadrant II ⇒ (π/2) < θ < (π)
Quadrant III ⇒ (π) < θ < (3π/2)
Quadrant IV⇒ (3π/2) < θ < (2π)
When θ = 2π/3
∴ (π/2) < θ < (π)
So, The angle 2pi/3 terminate in quadrant II

The answer to this is:
Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10 ÷ 190 = 5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175 = 14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.
