Answer:

A. distributive property

Answer:. Distributive property

Answer:

see below

Step-by-step explanation:

-15 = 2x + 1

Subtract 1 from each side

-15-1 = 2x + 1-1

-16 = 2x

Divide each side by 2

-16/2 = 2x/2

-8 =x

Check

-15 = 2(-8) + 1

-15 = -16+1

-15 = -15

Answer:

-8

Step-by-step explanation:

subtract 2x to move it to the left side

-2x-15=1

add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1

-2x=16

divide by -2 to get x by its self

-2x=16/2x

Answer:

C

Step-by-step explanation:

Since events A and B occur independently, it means that if A occurs, B May or May Not occur, vice versa. (basically, event A and B can occur on its own or together which are not dependent on the other event)

For probability of A and B to occur, and that probability of A / Probability of B occurring are not dependent on each other at any circumstance, u need to multiply the P(A) and P(B) to find out the chances of A and B occurring.

Answer:

56 cm

Step-by-step explanation:

perimeter = the length of the sides.

4+5+5+5+4+10+13+10=56 cm

Answer:

56 cm

Step-by-step explanation:

The perimeter of a shape is just all the lengths added  together. So 5+5+5= 15 and 10+10+13=33 and 4+4=8. 15+33+8=56. Hence 56 is the answer

Step-by-step explanation:

The possible number of solutions is 2.

Two or more expressions with an Equal sign is called as Equation.

The given equations are x² + y²=9 and 9x+2y=16

The graph of first equation is circle and the graph of second equation is a line.

We know that a line can intersect a circle at most 2 times. So, the greatest possible number of solutions is 2.

First equation can be rewritten as x² + y²=3²

It is the standard form of a circle , where (h,k) is center and r is radius.

(x-h)² +(y-k)² =r² where (h,k) is center and r is radius.

In the above equation h=0,k=0 and r=3. It is a circle with radius 3 and centered at origin.

The second equation is 9x+2y=16

It is a linear equation.

Table of values.

Plot these points on a coordinate plane and connect them by a straight line.

From the below graph it is clear that the line and circle intersect each other at two points. So, the given system of equation have two solutions.

Hence, the possible number of solutions is 2.

Answer:

Area of Shaded Region ≈ 141.37 cm^2

Step-by-step explanation:

Given radius of 9 cm for the outer circle;

πr^2, ⇒ Substitute value of radius,

π * ( 9 )^2 ⇒ Square 9, keeping value in terms of π,

Area of Outer Circle; 81π

Provided a radius of 6 cm for the inner circle;

πr^2, ⇒ Substitute value of radius,

π * ( 6 )^2 ⇒ Square 6, keeping value in terms of π,

Area of Inner Circle; 36π

Take the shaded region to be the value of the inner circle ( area ) subtracted from the area of the outer circle;

Answer:

since lisa earns half of what mary does divide 62 into 2 which is 31

and she has 8 students.

she is paid twice as much in students, so lisa would earn more due to getting paid more with having more students, as she gets paid twice the amount from students she has, and if she had 20 she would get paid 40 but if you add 2x of the mass it will be 80, and mary will have 40.

Answer:

6

Step-by-step explanation:

First we must get the equation in slope intercept form

y=mx+b

where m is the slope and b is the y intercept

3x+4y=24

To get this equation in slope intercept form, we have to get y by itself.

First, subtract 3x from both sides

3x-3x+4y=24-3x

4y= -3x+24

Now, divide both sides by 4

4y/4=-3x/4+24/4

y=-3/4x+6

So the y intercept is 6

The y-intercept of the graph of the equation 3x + 4y = 24 is y = 6.

Given the equation of the graph in the question:

3x + 4y = 24

The y-intercept of a graph is simply the point where the graph crosses the y-axis, meaning that the x-coordinates must be zero.

To determine the y-intercept of the graph of the equation 3x + 4y = 24, replace x with 0 and solve for y:

3x + 4y = 24

Substitute x = 0 into the equation:

3(0) + 4y = 24

Simplifying, we get:

0 + 4y = 24

4y = 24

Divide both sides by 4, to isolate the y-variable:

y = 24/4

y = 6

Therefore, the graph intersects the y-axis at the point (0, 6).

The premium of the policy is $4,124.65.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The premium of an insurance policy is calculated based on the probability of an event occurring and the amount that will be paid out if the event occurs.

To calculate the premium of the policy in this case, we can use the following formula:

Premium = (Payout + Administrative Costs) x Probability of Event

Where:

Payout = $50,000

Administrative Costs = $55

Probability of Event = 8.1393% = 0.081393 (in decimal form)

Substituting these values into the formula, we get:

Premium = ($50,000 + $55) x 0.081393

Premium = $4,124.65

Therefore,

The premium of the policy is $4,124.65.

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'm going to paint you a picture in words of what this looks like on paper.  We have a train leaving from a point on your paper heading straight west.  We have another train leaving from the same point on your paper heading straight east.  This is the "opposite directions" that your problem gives you.  

Now let's make a table:

                distance       =        rate      *       time

Train 1

Train 2

We will fill in this table from the info in the problem then refer back to our drawing.  It says that one train is traveling 12 mph faster than the other train.  We don't know how fast "the other train" is going, so let's call that rate r.  If the first train is travelin 12 mph faster, that rate is r + 12.  Let's put that into the table

              distance        =        rate        *        time

Train 1                                        r

Train 2                                    (r + 12)

Then it says "after 2 hours", so the time for both trains is 2 hours:

              distance        =        rate        *        time

Train 1                                        r           *          2

Train 2                                  (r + 12)       *          2

Since distance = rate * time, the distance (or length of the arrow pointing straight west) for Train 1 is 2r.  The distance (or length of the arrow pointing straight east) for Train 2 is 2(r + 12) which is 2r + 24.  The distance between them (which is also the length of the whole entire arrow) is 232.  Thus:

2r + 2r + 24 = 232 and

4r = 208 so

r = 52

This means that Train 1 is traveling 52 mph and Train 2 is traveling 12 miles per hour faster than that at 64 mph
