Answer:
40 2/5Ibs or 
lbs
Step-by-step explanation:
Let weight of object on the moon be represented = Wm
weight of object on the Earth = We
In the above question, we are told:
The weight of an object on the moon is
5 of its weight on Earth.
Hence, mathematically, this is represented as:
5Wm = We
If a moon rock weighs 202 lbs on Earth
5Wm = 202lbs
Wm = 202lbs/5
Wm = Ibs
Therefore, the moon rock weighs Ibs on the moon.
Answer:
610 feet
Step-by-step explanation:
From the question :
1 scarf = 2.5 yards of yarn
84 scarves = x yards
Cross Multiply
1 scarf × x yards = 84 × 2.5 yards
x yards = 210 yards
Hence, 84 scarves require 210 yards
Converting yards to feet
1 yard = 3 feet
210 yards = x feet
x feet × 1 yard = 210 yards × 3 feet
x feet = 210 yards × 3 feet/1 yards
x feet = 610 feet
Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn
The second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
<h3>
Which statement is always true?</h3>
Remember that for integer numbers, we have the following properties:
- Commutative property: A + B = B + A
- Associative property: (A + B) + C = A + (B + C)
Now, in this case we know that a and b are integer numbers, first we can see that the second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
The other 3 statements are false. You can see it by evaluating a = 0 and b = 1.
