True statements:
a) x + y = y + x ⇒ commutative property of addition
b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication
d) (x + y) + z = x + (y + z) ⇒ associative property of addition
False statements:
c) x - y = y - x should be: x - y = - y + x
e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
Answer:
<h2>52500 kg</h2>
Step-by-step explanation:
Step one:
given data
mass of harvested peanuts = 14,000kg
size of land = 8-acre
Step two:
Required:
mass of harvested peanuts for a 30-acre land
let the mass be x
so, for 8-acre land the harvested mass is 14,000
hence for 30-acre land the harvested mass is x
cross multiply we have
8x=14,000*30
divide both sides by 8
x=420000/8
x=52500 kg
Answer:
193%
Step-by-step explanation:
