Answer:
1.) -5.1
2.) personally I would not convert the way the would. There is a quicker way of converting that to decimal so idk exactly what they are doing unfortunately I can't help with you at the moment. I would need more time.
3.) Point C is the the opposite of -3.3
4.) D. 5.3333333 is a rational number
5.) All the points on the graph could represent rational numbers
6.) Simply Divide 2 by 6 to get repeating decimal
7.) -20.75 should be correct
Step-by-step explanation:
Chickens have 1 head and 2 legs
rabbits had 1 head and 4 legs
total heads is 30
c+r=30
total legs is 98
2c+4r=98
divide by 2
c+2r=49
multiply top equation by -1 and add to 2nd equation
-c-r=-30
<u>c+2r=49 +</u>
0c+1r=19
r=19
sub back
c+r=30
c+19=30
minus 19
c=11
11 chickens
19 rabbits
Okay so first,
Confirm: Every time we have 7 large sugar skulls, that also makes 5 large sugar skulls. So if you have 132 <u>ALTOGETHER</u>, then you'd need to do some multiplication/division. First, divide 132 by 5, that equals 26 small sugar skulls. Lastly, 132 ÷ 7 = 18 large sugar skulls. So there are 26 small sugar skulls and 18 large sugar skulls.
(I hope that was right, I tried my best :)
