(2/6) × 24 = m
(1/3) × 24 × 3(to take out (1/3)) = m × 3
24 = m×3
24÷3 = m×3 ÷3
8 = m
m = 8
So the answer should be B. 8
Hope I can help :)
Answer:
we will mix 55 liters of 20% solution and 20 Liters of 50% solutions.
Step-by-step explanation:
let the 20% solution = x liters
let the 50% solution = y liters
total solution of the mixture of the two solutions in % = 28%
total solution of the mixture of the two solutions in liters = 75 liters
considering the total solutions given, we will have the following equations if we mix the solutions in equal proportion;
20x + 50y = 28 (75)
0.2x + 0.5y = 0.28(75)
0.2x + 0.5y = 21 -------equation 1
Also,
x + y = 75 ------equation 2
y = 75 - x
(substitute this into equation 1)
0.2x + 0.5(75 - x) = 21
0.2x + 37.5 - 0.5x = 21
0.2x - 0.5x = 21 - 37.5
-0.3x = -16.5
x = -16.5 / -0.3
x = 55 liters
Recall, y = 75 - x
y = 75 -55
y = 20 Liters
Thus, we will mix 55 liters of 20% solution and 20 Liters of 50% solutions.

Answer:
m∠ADC = 90°
Step-by-step explanation:
Since, AB║CD and side AD is a transverse intersecting these parallel lines,
m∠DAC + m∠ADC = 180° [Consecutive interior angles]
85° + m∠ADC = 180°
m∠ADC = 180 - 85
= 95°
Therefore, measure of angle ADC = 95° will be the answer.
