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
1/4 is the same as 1 * 0.25
We should fuigre it out by first doing 1.7x since we don't know the 2 different widths and lengths.
P= 2*length + 2*width(the distance around)
Question says...
2(1.7x)+2x = 28
3.4x+2x=28
5.4x=28
X= 28m divided by 5.4
x = 5.2m: the width The length is : 8.8m
Step-by-step explanation:
1280. 100% of students
X. 60% of student voting for Joan
X=1280•60/100
X=768
