Think of it as a riddle.

You need to eliminate and match one city to one transport to one person in the end.

-----------------------------------------------------------------------------------------------

Take a look at my diagram!*

Use each clue to eliminate the rows and columns until you have narrowed it down.

Below is my work. It would be too hard to explain every step of the way; it will work differently for everyone. Maybe look up the game "Telepathy". The concept is similar!

-----------------------------------------------------------------------------------------------

I first read the instructions, eliminating and boxing the possible and impossible options.

If I ever got down to one empty spot in a column or row, I'd make sure to circle that and frequently write it down.

If you're doing this right, you will always be progressing. Don't doubt yourself; don't overthink it. It's the game of narrowing down and elimination. If you find yourself stuck, write what you know down. Use logic. Make sure you always look for rows that you forgot to cross out, or empty spots that you missed. Reread the instructions! You will get there!

-----------------------------------------------------------------------------------------------

*The "eliminated" part is a bit confusing, they weren't entirely eliminated. It's just my thought process! I didn't continue to use it. Just remember to group the right things together!

Don't be scared of looking up the cities and if you don't know, their states!

Literal equations, please help! this one is confusing to me.

sertanlavr [38]

What is asked here is that you isolate y so that the equation takes the form of y = ..., where ... will be something that contains a, b and c but not y. So how do we get there? By applying some standard permutations to equations like so:

aby - b = c

First, we bring the -b term to the right hand side by adding b left and right:

aby -b+b = c+b

The -b and +b cancel out, so we get:

aby = c + b

Then, we divide left and right hand side by ab:

aby/ab = (c+b)/ab

Again, the ab/ab on the left cancels out (it is 1), so we get:

y = (c+b)/ab

And we're done!

So you have to know that it is allowed to add or subtract something (anything) to/from the left and right hand side of an equation. Likewise, you have to know that it is allowed to multiply or divide by something, as long as it isn't 0.

ITS DUE TODAY GRADES ARE FINAL TODAY PLS HELP ILL GIVE BRAINLIEST 0.5a + 8.75 > 13.25

nirvana33 [79]

Answer:

The answer is 9

Explanation: 

0.5a+8.75=13.25

We simplify the equation to the form, which is simple to understand

0.5a+8.75=13.25

We move all terms containing a to the left and all other terms to the right.

+ 0.5a=+13.25-8.75

We simplify left and right side of the equation.

+ 0.5a=+4.5

We divide both sides of the equation by 0.5 to get a.

a=9

If today’s UV index is 8, Erin will burn in 15 minutes without sunscreen. If Erin puts on lotion with an SPF of 25, how long wil

yan [13]

Today’s UV index is = 8

Erin will burn in = 15 minutes

Since, its given"The time it takes to burn without sunscreen multiplied by the SPF, or sun protection factor, is the time you can stay in the sun safely with sunscreen"

= $25\times15=375$

So, Erin will be protected for 375 minutes.

Inverse of f(x)=-5x+15

Otrada [13]

f(x) = -5x - 15

Let y = f(x)

y = -5x - 15

Switch the x and y places, and solve for y:

x = -5y - 15

-5y = x + 15

y = (x + 15)/-5

y = -(x/5) - 3

So the inverse of : f(x) = -5x - 15 is

-x/5 - 3
