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.

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of
Verizon [17]

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.
