Answer:
x = 16/5
Step-by-step explanation:
2x + 14 -34 = 4x - 11x + 4x - 4
2x - 20 = -3x - 4
5x = 16
Answer:
40 grams of 13% alcohol solution and 10 grams of 18% alcohol solution.
Step-by-step explanation:
13%(x) + 18%(50-x) = 14%*50g Multiply them all
0.13x + (9-0.18x) = 7
0.13x-0.18x + 9 = 7 Simplify the equation and subtract 0.13x from 0.18x
9-0.05x = 7 Add 0.05x to each side
9 = 7+0.05x Subtract 7 from both sides
0.05x = 2 Multiply each side by 100
5x = 200 Divide both sides by 5
x = 40
50 - 40 = 10
40 grams and 10 grams

Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
- supplementary angles are two angles whose sum is 180°
∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
Answer:
0.84
Step-by-step explanation:
1 - 0.4(0.4) = 1 - 0.16 = 0.84
Simply take the probability of the the outcome that is not " at least 1 win", which is the probability of 2 losses;
To find the probability multiply the probabilities along the branches.
144/12 is 12
so it is equally divided
