So, you need to do the same operation to each side.
Start out by subtracting 3 from each side
1/4 (20x+8) = -3
Then, multiply both sides by 4
40x+8 = -12
Then, subtract 8 from each side
40x = -20
divide both sides by 40 and you get
x=-1/2
Hope this helped!
2838=total
Women = 3X +5
Men = 4(3x+5)-3
Children= x
Men= 12x+17
Total= 16X +23
16x + 23 = 2838
16x = 2815
X = 2815/16
Answer: 125
He has 20%, or 0.2 of the shirts now he had then. This equals 25:
0.2x = 25
Divide both sides by 0.2
0.2x/0.2 = 25/0.2
x = 125
Answer:
x = -52
y = -11
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Hence:
x+y=-63
x-y=-41
y = x+41
(Apply Simultaneous Equations)
x+(x+41)=-63
2x+41=-63
2x=-63-41
2x=-104
x=-104/2
x=-52
Now:
y=-52+41
y=-11
50 + 12x - 7 + 6x + 11 = 180
18x + 54 = 180
18x = 126
x = 7 degrees
Angle A = 6x + 11
Angle A = 6(7) + 11
Angle A = 42 + 11
Angle A = 53 degrees
