For example 5^-2 has to be in a positive exponent form you would put it as a fraction 1/5 and make the exponent positive next to the 5. This is due to a flip which makes the exponent positive

Answer:

San Francisco is the fastest

Step-by-step explanation:

The reason why is because you have to get the hours the same soooo...

You can get all of the hours to 12. So Ph= 3hours so 3x4=12 and what you do on one side you have to do on the other. So 1689x4=6756 next M=2 hours so to get it to 12 you do 2x6=12. Then 913x6=5478. Next San=4 hours

4x3=12 next 3x2556=7668 Sooooooo.... Put the data together

In 12 hours Ph goes 6756 miles

In 12 hours M goes 5478 miles

In 12 hours San goes 7668 miles

So the answer is San because it has the biggest number

Hope this help have a good day :)

The answer should be 164, if the angles are vertical (across from another) they are the same so 164 times 1/2 is 82

Solve 3(x + 2) &gt;x<br>Please ​
Anon25 [30]

Answer:

x > −3

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x + 2) > x

Step 1: Simplify both sides of the inequality.

3x + 6 > x

Step 2: Subtract x from both sides.

3x + 6 − x > x − x

2x + 6 > 0

Step 3: Subtract 6 from both sides.

2x + 6 − 6 > 0 − 6

2x > −6

Step 4: Divide both sides by 2.

2x / 2 > −6 / 2

x > −3

Answer:

x > −3

Hope this helps :)
