Answer 1

Answer:

x=-3

Step-by-step explanation:

there are three x's and five one's so the equation is 3x+5

on the other side there are 2 negative x's and 10 negative one's so the equation is -2x-10

set them equal to each other

3x+5=-2x-10

5x=-15

Perimeter of the given polygon is equals to 64cm.

What is perimeter?

"Perimeter is defined as the total distance around the given shape."

Theorem used

Tangents drawn from a exterior point of a circle have equal length.

According to the question,

As shown in the diagram,

P, Q, R, and S are exterior points of a circle through which tangents are drawn.

Given,

Length of tangent PA = 13cm

Length of tangent SA= 9cm

Length of tangent RC = 4cm

Length of tangent QC =6cm

As per  stated theorem we get,

Length of tangent PB = 13cm

Length of tangent SD 9cm

Length of tangent RD = 4cm

Length of tangent QB =6cm

Perimeter of a given polygon = 13 +13 +9+9+4+4+6+6

                                                 = 64cm

Hence, perimeter of the given polygon is equals to 64cm.

Create a line segment that is exactly 10 units in length and has a midpoint of (-3,4)

Answers

Answer:  A segment AB with Endpoints A (-8, 4) and B (2,4) is a horizontal line segment with (-3,4) as the midpoint.

A segment CD with endpoints C(-3,9) and D(-3,-1) will create a vertical line segment with (-3,4) as the midpoint.

A line segment FG with endpoints F (-6,0) and G(0,8) is a diagonal line with a slope of 4/3 and its midpoint is (-3,4)

Step-by-step explanation: For a horizontal or vertical line segment, choose the x-value or the y value of the midpoint. subtract 5 to get the lower endpoint, add 5 to get the higher endpoint. Keep the other coordinate the same.

The diagonal line segment is based on the hypotenuse of a triangle with side lengths corresponding to the Pythagorean Triple 3,4,5  Add and subtract 3 to the x-value od the midpoint, add and subtract 4 to the y value of the midpoint and the hypotenuses will extend 5 units in both directions from the midpoint.

At a concert , tickets cost either $40 or $60. 700 tickets were sold at a cost of $33600, find how many $40 tickets were sold

Answers

Answer:

420 $40 tickets.

Step-by-step explanation:

Here is the explanation.

1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.

2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.

3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.

4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.

5. 420 x 40=16800 280x60=16800

6. There are 420 $40 tickets sold at the concert.

Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.
Suppose Bobby's cat and dog were 6 miles apart after 30 minutes. Write an equation to

Answers

Answer:

3x/2 =6

Step-by-step explanation:

The distance between the dog and cat is 6 miles. Then the equation is 30x = 6 or x = 0.2.

What is speed?

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{ Time }[/tex]

Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.

The speed of a cat is x. Then the speed of the dog is 2x.

The distance traveled by the cat in 30 minutes will be

[tex]\rm D_c = 30 \times x\\\\D_c = 30 \ x[/tex]

The distance traveled by the dog in 30 minutes will be

[tex]\rm D_d = 30 \times 2x\\\\D_d = 60 \ x[/tex]

Suppose Bobby's cat and dog were 6 miles apart after 30 minutes.

[tex]\rm D_d - D_c \ \ = 6\\\\60x - 30x = 6\\\\30x = 6[/tex]

What is the square root?

A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Let a number is a. Then this number in the form of square root can be written as,

[tex]a=\sqrt{a}\times \sqrt{a}[/tex]

The given algebraic equation in the problem is,

[tex](x+ 9)^2 = 25[/tex]

Take the square root, in both sides,

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 301 people entered the park, and the admission fees collected totaled 814 dollars. How many children and how many adults were admitted? Your answer is number of children equals number of adults equals

Answers

If you add it up it would be 340 people

Answer:

156 children145 adults

Step-by-step explanation:

Let number of adults be a and children be c

Then we have equations

a + c = 3014a + 1.5c = 814

From the first equation we get a = 301 - c, we substitute a in the second equation:

4(301 -c) + 1.5c = 8141204 - 4c + 1.5c = 8142.5c = 1204 - 8142.5c = 390c = 390/2.5c = 156

Then finding the value of a:

a = 301 - 156 = 145
