1/2
-1/2
Step-by-step explanation:
we know that
If a dilation produce a contraction that means that the absolute value of the scaling factor is less than 1
If a dilation produce an enlargement that means that the absolute value of the scaling factor is greater than 1
<u><em>Verify each case</em></u>
case 1) 2

----> is a enlargement
case 2) 1/2

----> is a contraction
case 3) -2

----> is a enlargement
case 4) -1/2

----> is a contraction
Answer:
it should be 680
Step-by-step explanation:
1 kilogram is 1000 grams
720*6=4320
5000-4320=680
A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee
