1/2+6 over 3 = x-3 over 2
Amanda [17]

Answer:

x = 7 1/3

Step-by-step explanation:

First, add 1/2 and 6

1/2 + 12/2 = 13/2 = 6 1/2

Our equation now:

13/2 over 3 - x - 3 over 2 = 0

Next, divide 13/2 by 3

13/2 divided by 3 = 13/6

Our equation now:

13/6 over 3 - (x - 3) over 2 = 0

Now, find common denominators and simplify

13/6 - ((x - 3) times 3) over 6 = 0

22 - 3x over 6 = 0

Multiply by six on both sides

22 - 3x = 0

Subtract 22 from both sides

-3x = -22

Divide by -1

3x = 22

Divide both sides of the equation by 3

x = 22/3

x = 7 1/3

Hope this helps!

Use the graph to estimate the X and Y intercepts:
torisob [31]

The intercepts according to the graph is the X intercept = 18 Y intercept = 16.

According to the statement

we have to find that the intercepts with the help of the graph.

So, For this purpose, we know that the

The intercepts are the points on a graph at which the graph crosses the two axes (x-axis and y-axis). The point where the graph crosses the x-axis is called the x-coordinate and the point where the graph crosses the y-axis is called the y-coordinate.

And according to the above definitions and the given figure of the graph, the intercepts x and y become

It appears that the line crosses x = 0 at 16 and y = 0 at 18

So, The intercepts according to the graph is the X intercept = 18 Y intercept = 16.

IgorLugansk [536]

Answer:

26°

Step-by-step explanation:

The measure of arc PRQ is 308°, so the measure of arc PQ is 52°.

Inscribed angles are half the arc angle, so the measure of ∠PRQ is 26°.
