Answer:

B and C

Step-by-step explanation:

7.2 - 3.6 is the original equation

B states that 7.2 + -3.6 is equivalent, and it is right because and positive and negative multiplied by each other gives a negative

C states that 7.2 + (-3.6) is equivalent, and it is also correct because it would still be a negative number because its subtracting

A and D would just add up so it wouldn't be equivalent to 7.2 - 3.6

kompoz [17]

Given:

Total savings = $400

Ratio of savings of Blake and Josh = 3:1

To find:

The saving of each.

Solution:

Let the savings of Blake and Josh are 3x and x respectively.

Savings of Blake = 3(100)=300

Savings of Josh =100

Therefore, the savings of Blake and Josh are $300 and $100 respectively.
