Answer:

3/6 or 1/2

Step-by-step explanation:

There are 2 even numbers on the spinner. It would be 2/4 or 1/2 for the probability the spinner will land on one of the numbers. The coin is a 1/2 probability you will land on tales. If you add both sides of the coin and the 4 numbers on the spinner you would get 6. You would then add only the even and tales together. That would be 3 out of 6.

Their is a 50% chance for both events cause

their is 2 even and 4 total numbers

2/4 = 1/2 which is 50%.

For coin

Their is 1 take and 2 sides

Y = x + 3<br> 4x + y = 18
Drupady [299]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+x+3=18

(4x+x)+(3)=18(Combine Like Terms)

5x+3=18

5x+3=18

Step 2: Subtract 3 from both sides.

5x+3−3=18−3

5x=15

Step 3: Divide both sides by 5.

5x/5 = 15/5

x=3

At what value of x do the graphs of the equations below intersect?
Bogdan [553]

Answer:

Step-by-step explanation:

The intersection is the point where two equations meet. It is calculated by substituting terms into the equations involved. For the given systems of equation, calculations are as follows:

2x - y = 6

y = 2x - 6

We substitute the equation above to the second equation.

5x + 10y = –10

5x + 10( 2x - 6 )= –10

Simplifying, 

5x + 20x - 60 = -10

25x = 50

x = 2

Therefore, the intersection has the value of x equal to 2.
