4. Ernesto loses 14.5 pounds in 7 months. Now he weighs 156.5 pounds. Which equation can be used to find how much he weighed before?
w - 14.5 = 156.5
the 7 months makes no difference.
thanks! :)
Hey Jman. Do you know Dannan? That is if you are in 7th grade.
To find out how much Ernesto weighed before losing 14.5 pounds, we can set up an equation. Let's assume his initial weight was 'x' pounds.
Given that he loses 14.5 pounds in 7 months and his current weight is 156.5 pounds, we can express this information as:
x - 14.5 = 156.5
This equation represents the initial weight 'x' minus the weight he lost (14.5 pounds), which gives his current weight (156.5 pounds).
Now, we can solve this equation to find the value of 'x', which is Ernesto's initial weight.
Adding 14.5 to both sides of the equation to isolate 'x', the equation becomes:
x = 156.5 + 14.5
Simplifying the equation:
x = 171
Therefore, Ernesto weighed 171 pounds before he lost 14.5 pounds.
