Answer:
The amount of flour added to each box was 0.64 kg
Step-by-step explanation:
Let
x ----> the amount of flour added to each box in kg
Remember that
1 kg=1,000 g
8,600 g=8,600/1,000=8.6 kg
we know that
The linear equation that represent this situation is
(8.6+x)=4(1.67+x)
Solve for x
8.6+x=6.68+4x
4x-x=8.6-6.68
3x=1.92
x=0.64 kg
Answer: " x = 16 ; - 4 " .

<u>Note</u>:
______________________________
-16 , +4 = -12 .
-16 * 4 = -64
______________________________
(x - 16)(x + 4) = 0 ;
______________________________
x = 16 ; - 4 .

35% = .35.
First, you make 35% into a fraction 35/100. Then make it into simplified form.
35 divided by 5 and 100 divided by 5 35/5 = 7 and 100/5 =20.
So,
35%=.35=35/100=7/20
7/20
is your answer
