Answer:
A = 76.85
B =65.28
Step-by-step explanation:
(30/100)A = 10 + (20/100)B
0.3A - 0.2B = 10 ...... equation (i)
(30/100)B + 35 = (20/100)A
0.2A - 0.3B = 35 ........ equation (ii)
From equation (i)
0.3A = 10 - 0.2B
A = (10 - 0.2b) / 0.3
A = 33.33 - 0.67B ........equation (iii)
Put equation (iii) into equation (ii)
0.2(33.33 - 0.67B) - 0.3B = 35
6.67 - 0.134B - 0.3B = 35
0.434B = 35 - 6.67
B = 28.33 / 0.434
B = 65. 275 = 65.28
Put B = 65.28 into equation (i)
0.3A - 0.2B = 10
0.3A - 0.2(65.28) = 10
0.3A - 13.056 = 10
0.3A = 10 + 13.056
A = 23.056/ 0.3
A = 76.85
Answer:
<h2>
y = -5</h2>
Step-by-step explanation:
y = 3x − 26
2x − y = 19
2x - (3x - 26) = 19
2x - 3x + 26 = 19
- x = - 7
x = 7
y = 3•7 -26 = 21 - 26 = - 5
Answer:
= 5
Step-by-step explanation:
Substitute the given values into the formula
16 = 
× 4(3 + )
16 = 2(3 + ) ( divide both sides by 2 )
8 = 3 + ( subtract 3 from both sides )
5 =
