Answer :
Let's denote the number of months Mr. Russell must diet as "m". Given that he wants to lose 5 pounds per month, we can set up the following equation:
180 - 5m = 145
To solve for "m," let's isolate the variable:
180 - 145 = 5m
35 = 5m
Now, divide both sides of the equation by 5:
35/5 = m
7 = m
Therefore, Mr. Russell must diet for 7 months to reach his goal weight of 145 pounds.
180 - 5m = 145
To solve for "m," let's isolate the variable:
180 - 145 = 5m
35 = 5m
Now, divide both sides of the equation by 5:
35/5 = m
7 = m
Therefore, Mr. Russell must diet for 7 months to reach his goal weight of 145 pounds.
180-5m= 145, and it will take 7 months.
If the current weight is 180, you subtract 5m (m being the months), which equals 145 (the goal)
180-5m= 145
To isolate the variable:
First, you want to draw a line vertically through the equal sign separating both sides of the equation. Next, you will subtract 180 from BOTH sides of the equation your new equation would be -5m= -35. After this, you will divide BOTH sides of the equation by -5 (or the coefficient), and your new equation would be m=7. M is the # of months.
180-5m= 145
-5m= -35
m= 7
