1x1 is 1. 1x2 is 2. Why is this? Use 2 sentences and briefly explain.
lianna [129]

"1 x 1" means whatever you want it to mean. There is nothing that says the operation "x" should be multiplication. There is nothing that says that "1" should even be a number. I could, just to be a regular A-hole, say that "1" is shorthand for a set of elements, and "x" is just a nice way of pairing "1" with itself, and I can call this a domain for a function I am about to define.

However, if we are being totally serious here, "x" means the operation of multiplication and "1" is a commonly understood concept referring to the idea of a single thing by itself. Multiplication is a short-cut for lengthy addition problems.

So 3x4 is a short cut for 3 + 3 + 3 + 3, or equivalently, 4 + 4 + 4. That's pretty much it. How many times do I add up 3? How many times to I add up 4?

So when you ask what is "1 x 1", you are really asking How many times do I add up 1? Well, you add up 1 just 1 time. That gives you 1.

How do I solve this? I feel like I'm over thinking everything. thanks.
sesenic [268]

Equation: 26=6(5−4f)

Step 1: Simplify both sides of the equation.

26=6(5−4f)

26=(6)(5)+(6)(−4f)(Distribute)

26=30+−24f

26=−24f+30

Step 2)Flip the equation.

−24f+30=26

Step 3)Subtract 30 from both sides.

−24f+30−30=26−30

−24f=−4

Step 4) Divide both sides by -24.

-24/-24f=-4/-24

f=1/6
