Diana purchases 6 pounds of strawberries and 4 pounds of apples for 18.90. Then she realized that this was not enough and purcha
Veronika [31]
<span>6 pounds of strawberries for x pounds and 4 pounds of apples for y pounds. = $18.90.
6x + 4y = 18.90
Then, you add 3 more pounds of each fruit which equals $10.17. 
3x + 3y = 10.17
Then you multiply by -2 which is (-6x) - 6y = -20.34. After that, you add that (read carefully) you would do this. (-6x) + 6x - 6y + 4y = -20.34 + 28.90.
-2y = -1.44 divided by -2.
Y = -1.44/-2
Y = $0.72 per pound of apples.</span><span>Now, plus in the value of Y in equation 2.
3x + 3y = 10.17
3x + 3 * 0.72 = 10.17.
3x + 2.16 = 10.17
-2.16
3x = 10.17 - 2.16
3x = 8.06 /3

Int total, X = $2.68 per pound of strawberry. Hope this helps just read it carefully. </span>

What percentage is 40kg of 1tonne?
shepuryov [24]

So using the conversion of 1 metric ton to kg, we see that there are 1000 kg in 1 ton. Then we can divide 40 by 1000 to find the decimal:

\frac{40}{1000}=0.04

Then to convert this decimal to a percentage, we must multiply by 100%:

0.04*100=4

So now we know that 40 kg is 4% of 1 ton.
