Explain how the commutative property of addition,the Associative property of addition and mental math can help you find 75.2+(57
4vir4ik [10]

Answer: The sum of 75.2+(57.376+24.8) is 157.376.

Explanation:

The commutative property of addition states that,

a+b=b+a

The associative property of addition states that,

a+(b+c)=(a+b)+a

The given expression is 75.2+(57.376+24.8).

First use commutative property of addition in the parenthesis.

75.2+(57.376+24.8)=75.2+(24.8+57.376)

Now use associative property of addition.

75.2+(24.8+57.376)=(75.2+24.8)+57.376

Now simplify the expression,

(75.2+24.8)+57.376=100+57.376

(75.2+24.8)+57.376=157.376

Therefore, the sum of 75.2+(57.376+24.8) is 157.376.

Two numbers have a difference of 0.85 and a sum of 1 what are the numbers?
soldier1979 [14.2K]
X - y = 0.85
x + y = 1
----------------add
2x = 1.85
x = 1.85/2
x = 0.925

x + y = 1
0.925 + y = 1
y = 1 - 0.925
y = 0.075

so ur 2 numbers are : 0.925 and 0.075
