For this case what we can do is the following rule of three.
5 pound ---> 12.50 $
x ------------> 7.50 $
Clearing x we have:
x = (7.50 / 12.50) * (5)
x = 3 pounds
Answer:
the weight of the package is:
x = 3 pounds
3n/7=24 multiply both sides by 7
3n=168 divide both sides by 3
n=56

Personally, learning the material in any way possible is a good thing to me.
Answer:
196
Step-by-step explanation:
4(-1)²×49
4×49=196
Work is shown!! have a good day
Since the 40 degree angle and the bottom left angle both have the same red curve on them, the two angles are equal. So, they are both 40 degrees.
With this, we can make the equation .
To continue: know that the three angles of any triangle add up to 180 degrees. One of the angles in the left triangle is 90 degrees, as shown by the symbol that looks like a square. We can now make an equation where we add up all three angles in the left triangle, and set it equal to 180, like this: .
Now that we have 2 equations, we can find what x and y are. Let's first list the equations we got:
Now solve.
x is 3, y is 1.
