12x-6>14x-2 graph it

Answers

Answer: 12x-6=14x-2

We move all terms to the left:

12x-6-(14x-2)=0

We get rid of parentheses

12x-14x+2-6=0

We add all the numbers together, and all the variables

-2x-4=0

We move all terms containing x to the left, all other terms to the right

-2x=4

x=4/-2

x=-2

Step-by-step explanation:

I think it maybe is 12x-6=14x-2

Answer:

Step-by-step explanation:

a)  90 degrees -  lines that are tangent to a circle form right angles

b) 67 degrees - triangles have an area of 180 degrees. Since point p is tangent it is 90 so you would do x+23+90 =180 and solve (23 being the given angle).

c) 43 degrees - similarily to question b) point p is tangent and triangles are a sum of 180 degrees you would do x+47+90 = 180 and solve

3 + 6 + 3 = 12. If there are 6 green tiles, the probability of getting a green tile is 6/12. That would be a 50% chance that you would pick a green. 50% converted into decimal form is 0.5

Can u explain how to get the answer???

Answers

Answer:

Since there are 8 sections and 3 are even

We consider that 3/8

We now multiply by 120 since they said 120 times it is spun

3/8 x 120 = 45

The answer is 45.

It's hard to explain how I got the answer but I gathered the info below to help me get it.

There are 8 different sections on the wheel. 5 are odd numbers and 3 are even. 5/8 chance of getting an odd number 3/8 chance of getting an even number. The wheel is spun 120 times.
