Answer:
750 mm, 7.5 cm
Step-by-step explanation:
Verify each case
case a) 2.5 km, 2,500 m
we know that
1 km ------> 1.000 m
so
2.5 km=2,500 m
therefore
The pair of measurements is equivalent
case b) 750 mm, 7.5 cm
1 cm ------> 10 mm m
7.5 cm=75 mm
<u>The pair of measurements is not equivalent</u>
case c) 3 m, 3,000 mm
1 m ------> 1.000 mm
3 m=3,000 mm
case d) 120 cm, 1.2 m
1 m ------> 100 cm
1.2 m=120 cm
cant help you out, there are no options
50 = 3x + 2
50 - 2 = 3x
48 = 3x
48/3 = 3x/3
16 = x
Jack has 16 friends.
x = 7.8
2.6 + x = 10.4
-2.6 -2.6
You do the inverse operations to find out x
