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.

Solve the system of linear equations by graphing, round the solution to the nearest tenth.
algol [13]
For this case we have the following system of equations:
 y = -0.25x + 4.7

y = 4.9x-1.64
 When solving the problem graphically we must take into account the following:
 1) The solution of the system of equations is given by the intersection of both functions.
 2) The solution is an ordered pair of the form (x, y)
 For this case we observe that the solution is given by:
 (x, y) = (1.23, 4.39)

 Note: see attached image.
 Answer:
 
The approximate solution to the system is (1.23, 4.39)
