x=2,y=7→ y=11-2x;4x-3y=-13
x=5,y=2→ 2x+y=12;x=9−2y
x=3,y=5→ y=10+x;-3x+3y=30
x=7,y=3→ x+3y=16;2x−y=11
Hope this helps :)
The boy is 15 because twice the age of his sister is 12, then you add the three years to it and get 15
0.000045 = <span>00.00045 /10
=</span><span> 000.0045 / 100
</span>= 0000.045 / 1 000
= 00000.45 / 10 000
<span>= 000004.5 / 100 000 = 4.5 * 10^(-5)
That is in</span><span> scientific notation
I hope that helps
