Answer:
Step-by-step explanation:
x + 2y = 8 -----------(I)
x - 2y = -4 -----------(II)
Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'
(I) x + 2y = 8
(II) <u>x - 2y = -4</u><u> </u>{Now add}
2x = 4
x = 4/2
x = 2
Substitute x = 2 in equation (I)
2 + 2y = 8
2y = 8 - 2
2y = 6
y = 6/2
y = 3
Answer:
4,784
Step-by-step explanation:
Find how many are defective
Convert 8% to a decimal
8/100=0.08
Multiply
5,200*0.08=416
416 are defective, to find how many aren't subtract the defective from the whole
5,200-416=4784
So, 4,784 are not defective
Hope this helps! :)
