Answer and Step-by-step explanation:

We are given: 18x - 2(3x + 1) = 5x - 16

First, lets distribute the -2 to the 3x and 1.

18x - 6x - 2 = 5x - 16

Now, we combine like terms.

12x - 2 = 5x - 16

Next, we add 2 to each side.

12x = 5x -14

Now, we subtract 5x from both sides.

7x = -14

Finally, we divide by 7 on both sides.

x = -2

Statements: Reasons:

18x - 2(3x + 1) = 5x - 16 Given

18x - 6x - 2 = 5x - 16 Distributive Property of Equality

12x - 2 = 5x - 16 Combine like terms

12x = 5x -14 Addition Property of Equality

7x = -14 Subtraction Property of Equality

x = -2 Division Property of Equality

Determined be whether the solution to 32=6(1)-4

igomit [66]

Answer:

false

Step-by-step explanation:

32 = 6(1) - 4

According to PEMDAS (parentheses/exponents | multiplication/division | additions/subtraction), we should multiply first.

32 = 6 - 4

Now let's subtract.

32 = 2

This statement is incorrect; therefore it is not true.

nexus9112 [7]

Answer: Option D :3.85 units.

Step-by-step explanation: Diameter is the longest chord of any circle . It is a straight line passing through the center of the circle and touches the circle at two points. Radius is a line drawn from the center of circle to the circumference. Radius is half of diameter.In the given figure the blue line is diameter .The diameter is the blue line which equals 7.7 units.Radius is half of diameter .Radius = 7.7÷2=3.85 units.

Option D is the right answer.

Determine the coordinates of the point on the unit circle corresponding to the given central angle. If necessary round your resu

Olenka [21]

Answer:

Option A. (-1, 0)

Step-by-step explanation:

In the figure attached,

Circle O is a unit circle (having radius r = 1 unit)

If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,

x = r.cosθ

x = 1.cosθ = cosθ

and y = r.sinθ

y = 1.sinθ = sinθ

Therefore, coordinates representing the point A will be (cosθ, sinθ).

As per question the given point A is lying at P (a point having central angle θ = 180°)

Coordinates of point P will be

(x', y') → (cos180°, sin180°)

→ (-1, 0)

Therefore, Option A will be the answer.
