If the weight of a package is multiplied by 5/7 the result is 40.5 pounds.Find the weight of the package.
please???I am so far really bad with pre-algebra!!!can someone please teach me how to do this step by step??
5/7x = 40.5
x = 40.5 / 5/7
x = 40.5 * 7/5
x = 283.5/5
x = 56.7 = 56 7/10
can someone please explain to me what the Answer is and also can someone please explain to me how to slove this question step by step???
Please??!!
thanks we both needed that help with pre algebra mrs.sue!!!thank you!!!
You're very welcome, Kate.
To solve this problem, we can set up an equation. Let's call the weight of the package "x".
According to the problem, when the weight of the package is multiplied by 5/7, the result is 40.5 pounds.
So, we can write the equation as:
(5/7) * x = 40.5
To find the weight of the package, we need to isolate x.
We can do this by multiplying both sides of the equation by the reciprocal of 5/7, which is 7/5, so that the coefficient of x becomes 1:
(5/7) * x * (7/5) = 40.5 * (7/5)
Simplifying, we get:
x = (40.5 * 7) / 5
Now, we just need to solve this equation to find the value of x:
x = 283.5 / 5
x = 56.7 pounds
Therefore, the weight of the package is 56.7 pounds.
