Answer:
Paul filled 4 bags on Sunday.
Step-by-step explanation:
Since each bag that was filled weighed 5 pounds then we can use the following equation to solve for the amount of bags, where (x) is the number of bags filled on Saturday and (y) is the number of bags filled on Sunday.
5x + 5y = 30
Now since we are told that on Saturday Paul filled 2 bags then we would only be left with the variable y (number of bags filled on Sunday). We can solve for y
5(2) + 5y = 30
10 + 5y = 30 ... subtract 10 on both sides
5y = 20 ... divide by 5 on both sides
y = 4
Finally, we can see that Paul filled 4 bags on Sunday.
If 300 reduced by twice your age is equal to 192, your age (represented by x) would be 54 years old.
To solve the given equation "300 reduced by twice my age is 192," we can represent the equation using algebraic notation.
Let's assume "x" represents your age. The equation can be written as:
300 - 2x = 192
Now, let's solve for x:
300 - 192 = 2x
108 = 2x
54 = x
Therefore, if 300 reduced by twice your age is equal to 192, your age (represented by x) would be 54 years old.

Question:
Which three-dimensional figures have lateral faces that are polygons? check all that apply.
- cones
- cylinders
- hemispheres
- prisms
- pyramids
- spheres
Answer:
The correct choices are;
- prisms and
- pyramids
Step-by-step explanation:
A polygon is a figure closed or bounded with several straight line segments and polygons are named based on how many sides, side size and sizes of angles that they have present.
A three sided polygon for example is called a triangle
A lateral face are the faces of a prism except the base
Based on the definitions, we note that out of the options, only prisms, and pyramids have lateral faces that are made up entirely of straight line segments, hence polygons. Therefore, the correct choices are prisms and pyramids.
Answer:
Actually the correct is Cylinders, Prisms, and Pyramids. I just did it
Step-by-step explanation:
1 - 4 = -3. -3 - 4 = -11.
subtract by -4 until you have 8 numbers.
then add al the numbers together.
1+-3+-7+-11+-15+-19+-23+-27 = -104
