The points that are graphed would be (0,-1) and (1/2, 2).
Reasoning: Slope is 2, and the y-intercept is (0,-1)

There are 1000 m in 1 km.
441.96/1000 = 0.44196
0.44196 km
22 -
There are 1000 mg in 1 g.
5700/1000 = 5.7
5.7 g
23 -
There are 1000 mL in 1 L.
0.946 * 1000 = 946
946 mL
24 -
There are 10 mm in 1 cm.
60(10)=600
600/50=12
12 beads
25 -
There are 1000 mL in 1 L.
1500(2)=3000
3000/1000=3
3 L
26 -
There are 100 cm in 1 m.
110(100)=11000
11000-8=10992
10992 cm
1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
For this, you would use simultaneous equations.
w=walnuts
a=almonds
3w+6a=51
5w+4a=55
Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:
15w+12a=165
6w+12a=102
Then take them away to leave w:
9w=163
Then solve:
w=163/9
= 18.11111111...
Then round it to 2 decimal places as the measurement is currency.
So 1 pound of walnuts equals $18.11
