Which inequality is equivalent to -m ≥ 15? A. m ≥ 15
B. m ≥ -15
C. m ≤ -15
D. m ≤ 15

b I think

Step-by-step explanation:

C

Step-by-step explanation:

To solve this equation, since m is negative you need to get rid of that negative by dividing each side by -1. this will leave m and make 15, -15. so the equation will be c, m is less than or equal to -15.

Part A.  

x + y = 60  

x = 30 + y

Part B. Jacob spends 15 doing freehand services and 45 minutes running on the treadmill .

Part C.  

It's not possible from the arithmetic perspective, because if x = 40, therefore:  

x + y ≠ 60

x ≠ 30 + y

Step-by-step explanation:  

1. Let's review the information given to us to answer the question correctly:

Time Jacob spends in the gym everyday = 60 minutes  

Time Jacob runs on the treadmill = 30 minutes longer than he does freehand exercises  

2. Write a pair of linear equations to show the relationship between the number of minutes Jacob does freehand exercises  and the number of  minutes he runs on the treadmill .

Let y to represent the time Jacob does freehand exercises  

Let x to represent the time Jacob runs on the treadmill  

x + y = 60  

x = 30 + y

3. How much time does Jacob spend doing freehand exercises?

Let's solve for x and y, this way:  

x + y = 60  

x = 30 + y  

x = 60 - y

x = 30 + y

60 - y = 30 + y

- y - y = 30 - 60

-2y = -30

y = -30/-2

y = 15  ⇒ x = 30 + 15 = 45

Jacob spends 15 doing freehand services and 45 minutes running on the treadmill

4. Is it possible for Jacob to have spent 40 minutes running on the treadmill?

It's not possible from the arithmetic perspective, because if x = 40, therefore:  

x + y ≠ 60  

x ≠ 30 + y
